OPINION
NIEMEYER, Circuit Judge:Joseph Wayne Pratt was convicted on five drug trafficking counts: one count of conspiracy to traffic in cocaine, three counts of attempt to possess cocaine with the intent to distribute it, and one count of using a communication facility — a telephone — to facilitate one of the attempt violations. The district court sentenced Pratt to 188 months’ imprisonment.
On appeal, Pratt contends (1) that the evidence was insufficient to support the convictions on the three attempt counts and that, with their dismissal, the court must also dismiss the count charging him with using a communication facility to aid in one of the attempts; (2) that his right to due process was violated when the district court permitted a government agent to enter the jury room to “cue up” an audiotape on the tape recording machine to a portion requested by the jury; (3) that the district court abused its discretion in admitting audiotape transcripts; (4) that the district court abused its discretion in refusing to grant a multiple-conspiracy instruction; (5) that the district court abused its discretion in refusing to grant an entrapment instruction; (6) that Pratt was entitled to a new trial because of the cumulative effect of various allegations of pretrial misconduct by the government; and (7) that the district court, in sentencing Pratt, erroneously enhanced his Criminal History Category by taking into account two orders of “civil contempt for failure to pay child support.”
For the reasons that follow, we affirm.
I
Joseph Pratt was involved in a longtime cocaine-distribution conspiracy, beginning in the spring of 1996 and continuing to February 2002, which involved Christopher Lamont Hill, Mark Beale, Curtis Campbell, Larry Kelly, and others. Kelly was arrested, pleaded guilty in 1999 to drug conspiracy, and was sentenced to 210 months’ imprisonment. After his sentence, he agreed to cooperate with a law enforcement investigation in Westmore-land County, Virginia, in exchange for a promise to have his sentence reduced.
During the period of cooperation, Kelly traveled with the co-conspirators, wearing an audio recording device by which he recorded conversations with Pratt, beginning in September 1999 and ending in the spring of 2000. Upon completion of this investigation, a grand jury indicted Pratt on counts of conspiracy, attempted trafficking on September 9,1999, February 10, 2000, and March 30, 2000, and use of a communication facility to aid and facilitate the March 30 attempt. A jury convicted Pratt on all counts, and following sentencing, Pratt filed this appeal.
II
Pratt’s principal argument on appeal challenges the sufficiency of evidence on Counts 3, 4, 5, and 6. Counts 3 through 5, which incorporated the conspiracy allegations of Count 1, alleged additional conduct specific to September 9, 1999, February 10, 2000, and March 30, 2000, stating that on each occasion Pratt attempted to possess cocaine with the intent of distributing it or aiding and abetting such possession, each in violation of 21 U.S.C. § 846, 21 *135U.S.C. § 841(a)(1), and 18 U.S.C. § 2. Count 6 charged Pratt with using a telephone in the commission of the March 30 attempt violation charged in Count 5, in violation of 21 U.S.C. § 843(b).
Pratt contends that the “words” that were recorded on the audiotapes and offered to prove the offenses alleged in Counts 3 through 5 constituted the only evidence to support his convictions on those counts and that they are insufficient proof of the crime of attempt. He asserts:
There is no evidence that Pratt possessed the specified drugs or money necessary to effect the transactions discussed on those dates ... or that he brought together someone [with] someone else who actually did have the specified drugs to sell in the same place as a prospective purchaser who actually had the money to buy. There was therefore insufficient proof of the “substantial step” required by law to support those convictions.
An attempt to commit a crime, which is recognized as a crime distinct from the crime intended by the attempt, punishes conduct that puts in motion events that would, from the defendant’s point of view, result in the commission of a crime but for some intervening circumstance. And 21 U.S.C. § 846 specifically punishes an attempt to violate the drug trafficking laws. While the statute does not define the elements of an attempt, the crime is nonetheless well understood in the law, and its elements are not generally disputed.
To establish that a defendant committed the crime of attempt, the government must prove that (1) the defendant had the requisite intent to commit a crime; (2) the defendant undertook a direct act in a course of conduct planned to culminate in his commission of the crime; (3) the act was substantial, in that it was strongly corroborative of the defendant’s criminal purpose; and (4) the act fell short of the commission of the intended crime due to intervening circumstances. See, e.g., United States v. Neal, 78 F.3d 901, 906 (4th Cir.1996); United States v. Sutton, 961 F.2d 476, 478 (4th Cir.1992); United States v. McFadden, 739 F.2d 149, 152 (4th Cir.1984) (developing Fourth Circuit’s standard from § 5.01 of the Model Penal Code); Model Penal Code § 5.01(l)(c); Clark and Marshall’s Treatise on the Law of Crimes § 4.06 (Melvin F. Wingersky ed., 6th ed. 1958). The Model Penal Code, from which this court’s formulation was originally drawn, provides the following list of acts strongly corroborating a defendant’s criminal purpose:
(a) lying in wait, searching for or following the contemplated victim of the crime;
(b) enticing or seeking to entice the contemplated victim of the crime to go to the place contemplated for its commission;
(c) reconnoitering the place contemplated for the commission of the crime;
(d) unlawful entry of a structure, vehicle or enclosure in which it is contemplated that the crime will be committed;
(e) possession of materials to be employed in the commission of a crime, that are specially designed for such unlawful use or that can serve no lawful purpose of the actor under the circumstances;
(f) possession, collection or fabrication of materials to be employed in the commission of the crime, at or near the place contemplated for its commission, if such possession, collection or fabrication serves no lawful purpose of the actor under the circumstances;
*136(g) soliciting an innocent agent to engage in conduct constituting an element of the crime.
Model Penal Code § 5.01(2).
Mere preparation for the commission of a crime, however, does not constitute an attempt to commit a crime. But if preparation comes so near to the accomplishment of the crime that it becomes probable that the crime will be committed absent an outside intervening circumstance, the preparation may become an attempt. Thus the line between mere preparation and a substantial act done toward the commission of a crime is inherently fact-intensive, and it is not always a clear one. See Neal, 78 F.3d at 906 (citing United States v. Coplon, 185 F.2d 629, 633 (2d Cir.1950) (Learned Hand, C.J.) (“The decisions are too numerous to cite, and would not help much anyway, for there is, and obviously can be, no definite line [between preparation and attempt]”)). To determine whether conduct is preparation or an attempt, a court must assess how probable it would have been that the crime would have been committed — at least as perceived by the defendant — had intervening circumstances not occurred. Applying this standard, it becomes clear that the direct, substantial act toward the commission of a crime need not be the last possible act before its commission. An attempt comprises any substantial act in a progression of conduct that is meant to culminate in the commission of the crime intended.
Thus, while words and discussions would usually be considered preparations for most crimes, a specific discussion could be so final in nature that it left little doubt that a crime was intended and would be committed. In Neal, we held that the discussion leading to an agreement to engage in crack cocaine transactions, along with corroborative evidence, was a substantial step toward the commission of the drug transaction when the defendant Neal left the discussion with a final, unconditional agreement that he would obtain the crack cocaine. 78 F.3d at 906. We found it helpful to the finding in that case that when Neal was arrested, he tried to evade police, and after his arrest, police discovered drugs and paraphernalia about his mother’s house. Id. at 907; see also Model Penal Code § 5.01 (2)(g) (providing that a substantial step may be the “solicit[ation] [of] an innocent agent to engage in conduct constituting an element of the crime”).
We believe that the factual record presented in this case is analogous to the record presented to the court in Neal and supports the jury’s conviction of Pratt on Counts 3, 4, and 5. In this case, Pratt had over several years trafficked in cocaine as a buyer, seller, and middleman, working with multiple co-conspirators. As the indictment charged:
The defendants [including Pratt] and their co-conspirators played different roles, took upon themselves different tasks, and participated in the affairs of the conspiracy through various criminal acts. The defendants made themselves and their services available at times throughout the conspiracy and would participate in the selected purchases and sales of cocaine hydrochloride and cocaine base, commonly known as “crack,” on an as-needed basis. The defendants and their co-conspirators adopted and carried out various roles at various times during the life of the conspiracy.
The government presented evidence to support these allegations.
In the context of this conspiratorial conduct, Counts 3, 4, and 5 charged Pratt with attempts to function as a middleman in intended drug transactions on September 9, February 10, and March 30. The evidence presented by the government in-*137eluded both the evidence with respect to the general conspiracy and evidence supplied by audiotape recordings consisting of discussions and actions taken by Pratt on September 9, 1999, February 10, 2000, and March 30, 2000, and it tended to prove Pratt’s function as a middleman in drug trafficking.
The evidence showed that on September 9, after Kelly and Pratt reached agreement that Kelly would sell cocaine that Pratt would obtain from Lamont Hill, Kelly drove Pratt in Kelly’s car to meet Mark Beale, the intended purchaser of the drugs. Pratt gave Kelly instructions, as they drove, on how to get to Beale’s residence. After they arrived, Pratt introduced Beale to Kelly, and the group confirmed the price. Specifically, when Beale entered the car and joined Kelly and Pratt, Beale confirmed the agreement that he would purchase “Quarter pound. Eighth [of a kilogram] of base” at “thirty-six hundred [dollars].” Completion of the deal had to await Beale’s obtaining the cash from his customer. Beale promised to get back by “tomorrow,” “[t]omorrow evening, for sure.” In the context of Pratt’s overall conspiratorial conduct, those specific actions establish a “substantial step” directed toward the commission of a drug transaction in which Pratt intended to be the middleman, aiding or abetting the transaction. See 18 U.S.C. § 2; 21 U.S.C. § 841(a)(1); Model Penal Code § 5.01(3) (providing that “[a] person, who engages in conduct designed to aid another to commit a crime that would establish his complicity ... if the crime were committed by such other person, is guilty of an attempt”).
Similarly, on February 10, 2000, Pratt again performed his middleman role, presenting to Kelly an offer from Pratt’s cousin to sell Kelly 62 grams of cocaine for $2,000. The evidence showed personal effort on the part of Pratt to facilitate the deal. When Kelly resisted the high price, Pratt assured him that with his seller, “He give[s] you extra every time.” Pratt and Kelly eventually agreed that in the proposed transaction, Kelly would accompany Pratt to meet the seller. Thus, Pratt presented the offer to Kelly, encouraged him to accept it, and agreed to the details of the transaction. Again performing as a middleman, Pratt took steps toward the intended completion of a drug transaction to which he would have been an aider and abettor.
Finally, on March 30, 2000, Pratt again attempted to bring about a drug transaction when he called Kelly by telephone to set a final time of “two o’clock tomorrow,” “exactly two o’clock now,” for the transaction. By establishing the specific time for the deal to take place and passing the information on to Kelly, Pratt not only took substantial steps toward completion of the transaction but completed his function as middleman in a deal for which, had it transpired, he would again have been liable for aiding and abetting.
The incidents on September 9, February 10, and March 30 involved more than mere words or preparation. The evidence is sufficient for a rational jury to conclude that Pratt was a drug dealer who had been participating in a longtime drug conspiracy and that, during these incidents, he functioned as a middleman, intending that drug transactions take place and assisting the conspirators to complete them. There can be little doubt that, but for outside intervention, the transactions that Pratt intended would have occurred, in violation of 21 U.S.C. § 841, and that Pratt would have been an aider and abettor, in violation of 18 U.S.C. § 2. The evidence in the record is therefore sufficient to enable a rational jury to find Pratt guilty beyond a reasonable doubt of criminal attempt, in violation of 21 U.S.C. § 846.
*138Because the evidence was sufficient to support the convictions on Counts 3, 4, and 5, it was also sufficient to support the conviction on Count 6, charging that the attempt described in Count 5 was facilitated by a telephone, as there is no dispute that a telephone was used in the March 30 incident.
Ill
Pratt next contends that his right to due process was violated when the district court directed a government agent to enter the jury room and “cue up” an audiotape on the tape recorder to a specific location requested by the jury without also providing for Pratt’s presence during the process.
During deliberations, the jury sent the district judge a note stating, “We cannot find the dialogue on tape 10 B. We want to listen to line 91. Can we obtain assistance in finding this section of the tape?” The district judge directed the tape-recorder technician, a special agent of the Drug Enforcement Administration, to find the place on the tape requested by the jury, and he ordered that a court security officer accompany the technician “to watch him, and he is to have no conversation with the jury and try to influence them in any way.” The technician completed the task within a few minutes, and jury deliberations resumed.
Pratt’s counsel, who was in the courtroom but not in the jury room where the audiotape was cued up, objected.
Pratt now contends that ordering the technician and the court security officer to the jury room without Pratt’s being present with counsel violated Federal Rule of Criminal Procedure 43. He argues that this conduct is more egregious than simply playing an entire tape for the jury because the technician here was “in effect directing jurors to a particular piece of tape evidence, and not merely conducting the ministerial task of playing an entire tape.” Pratt notes that even playing an entire tape requires a new trial, citing United States v. Freeman, 634 F.2d 1267 (10th Cir.1980), and our unpublished decision in United States v. Jayson, No. 93-5879, 1995 WL 234249 (4th Cir. Apr. 21, 1995).
Rule 43(a) requires that the defendant “be present at ... every trial stage, including jury impanelment and the return of the verdict.”* Cases interpreting this rule have held that playing a tape for the jury outside of the defendant’s presence violates the rule. See United States v. Brown, 832 F.2d 128 (9th Cir.1987); Freeman, 634 F.2d at 1267. A violation of Rule 43 is subject to harmless-error review, and the judgment “may stand only if there is no reasonable possibility that the practice complained of might have contributed to the conviction.” United States v. Camacho, 955 F.2d 950, 955 (4th Cir.1992) (citing United States v. Hasting, 461 U.S. 499, 506, 103 S.Ct. 1974, 76 L.Ed.2d 96 (1983)).
There is no suggestion in this case that the district court’s order was not carried out as directed by the court, and we presume therefore that it was because the court assured compliance through the presence of the court’s own security officer. Under the court’s order, as enforced by the court’s security officer, the technician entered a jury room, cued up the audiotape to the designated spot, and exited, without conversing with the jury or *139remaining present during its deliberations. In these circumstances, the technician would not have overheard or affected any deliberations, nor would he have done anything other than the ministerial task of cuing up the audiotape. The technician’s task might be analogized to replacing a burned out light bulb in the jury room or carrying into the jury room a large exhibit that had been admitted into evidence.
The incident in this case is unlike a situation where a technician plays a tape to a jury while the jury listens to the evidence as part of its deliberations. Cf., e.g., Freeman, 634 F.2d at 1268. In such a circumstance, the technician would be present during actual deliberations, and the burden on the government to demonstrate harmlessness would be significantly greater.
The risk attendant to the practice of sending a person into the jury room to cue up an audiotape on a tape recorder is sufficiently great that we do not condone it. The jury’s request undoubtedly could have been accommodated without raising a Rule 43 question. On the record before us, however, we conclude that there is no “reasonable possibility” that the technician’s cuing up the tape and then leaving the jury room had any effect on the outcome of Pratt’s trial. See Camacho, 955 F.2d at 955.
IV
The only other argument advanced by Pratt meriting some discussion is his contention that the district court erred in enhancing his Criminal History Category during sentencing by taking into account what Pratt characterizes as “two civil nonsupport proceedings” in which Pratt was found in contempt and ordered to serve time in prison. He argues that because the sentences were for “civil contempt,” they should not be included as part of Pratt’s “prior criminal behavior.” U.S.S.G. Chap. 4, pt. A, introductory cmt. (2002).
Section 4A1.1 of the Sentencing Guidelines, which specifies how a defendant’s prior criminal history is used to determine the defendant’s Criminal History Category, provides that two criminal history points are to be added for each “prior sentence of imprisonment of at least sixty days,” U.S.S.G. § 4Al.l(b), and sentences of imprisonment for “contempt of court” and “non-support” qualify as such prior sentences, provided they are for “at least thirty days,” id. § 4A1.2(e)(l).
In this case, the record shows that Pratt appeared before State court on November 12, 1998, in response to a show cause order for his failure to pay child support. The court then established that Pratt had accumulated an arrearage in child support payments and ordered him to begin making supplemental support payments to reduce the arrearage. Two months later, when Pratt had failed to comply with the court’s order, the court “sentenced the defendant to serve six months in jail.”
A few months after Pratt was released from jail, he again accumulated a significant arrearage in nonsupport payments. On August 25, 1999, the State court “ordered the defendant to serve 6 months in jail,” but it also ordered that the sentence could be purged “if the defendant paid $1,500 to the petitioner.” Pratt appealed that order but did not post the required bond and the case was remanded to the domestic relations court. At the September 27, 1999 disposition hearing that followed, Pratt did not appear, and the court issued a warrant to the sheriff to arrest Pratt “for service of the 6-month jail sentence.” Pratt was never apprehended, and *140the record shows that he “remain[ed] on an ‘escape status.’ ”
Thus, the record reveals that Pratt was punished twice by a six-month sentence for a definite period with no mention of any opportunity to purge the sentence. While the second order initially entitled Pratt to purge the sentence, it was converted into a definite six-month jail sentence when Pratt failed to appear.
While Pratt argues that these sentences were for “civil contempt,” the record belies his claim, indicating that they were six-month sentences entered for punishment and therefore were criminal contempt sentences. The distinction between a sentence for civil contempt and a sentence for criminal attempt is well established. A civil contempt sentence aims to “coerce the defendant to do the thing required,” whereas a sentence for criminal contempt “operates ... solely as punishment for the completed act of disobedience.” Gompers v. Bucks Stove & Range Co., 221 U.S. 418, 442-43, 31 S.Ct. 492, 55 L.Ed. 797 (1911); accord Hicks v. Feiock, 485 U.S. 624, 631-33, 108 S.Ct. 1423, 99 L.Ed.2d 721 (1988); Carbon Fuel Co. v. United Mine Workers, 517 F.2d 1348, 1349 (4th Cir.1975). In Hicks, the Supreme Court articulated the test for making the distinction: “[I]t is remedial if ‘the defendant stands committed unless and until he performs the affirmative act required by the court’s order,’ and is punitive if ‘the sentence is limited to imprisonment for a definite period.’ ” Hicks, 485 U.S. at 632, 108 S.Ct. 1423 (quoting Gompers, 221 U.S. at 442, 31 S.Ct. 492).
It is readily apparent that both six-month sentences imposed on Pratt for failing to comply with court orders were “for a definite period” and could not be purged by any affirmative act. The district court did not err in considering Pratt’s two six-month sentences for criminal contempt in determining his Criminal History Category.
V
Pratt’s other arguments do not merit extensive discussion. First, he objects to the government’s use at trial of transcripts of taped conversations, but he has not demonstrated that the transcripts were in material variance with the audiotapes introduced into evidence. Moreover, the district court gave the jury an instruction that in the event of a variance between tapes and transcripts, the tapes controlled, thus protecting against any potential prejudice if a variance did exist. See United States v. Collazo, 732 F.2d 1200, 1203 (4th Cir.1984).
Pratt also contends that the district court abused its discretion in refusing to grant his requests for instructions on multiple conspiracies and entrapment. But he has failed to point to evidence that justified his requests. With respect to whether multiple conspiracies were shown, the evidence indicates that the three defendants had extensive drug-related ties to one .another and that they had the same objectives, methods, and products in the same geographical area, thus participating in a single conspiracy. See United States v. Crockett, 813 F.2d 1310, 1316-17 (4th Cir.1987). And with respect to entrapment, Pratt failed to show that the government’s use of Kelly as an informant induced him to commit a crime that he was previously indisposed to do. See United States v. DeVore, 423 F.2d 1069, 1071 (4th Cir.1970).
Pointing to what he contends were an array of delays, peculiar strategies, discovery failures, and other pretrial conduct by the government, Pratt argues that the “cumulative effect” of the government’s activities amounted to vindictive prosecution. *141We have considered each of Pratt’s contentions and also taken them in the aggregate, yet we find that his contentions fall substantially short of what is required to carry his burden. See United States v. Williams, 47 F.3d 658, 662-65 (4th Cir.1995).
VI
For the reasons given, we affirm the judgment of the district court.
AFFIRMED
The form of Rule 43(a) that applied at the time of trial in this case required that the defendant "be present at ... every stage of the trial including the impaneling of the jury and the return of the verdict,” but no change of meaning was effected by the 2002 amendments to this rule.
