On appeal from a sentence imposed upon revocation of probation appellant contends that resentencing is required because the trial court relied upon a facially erroneous sentencing guidelines scoresheet. We find error, in that the guidelines scoresheet utilized by the sentencing judge erroneously scored 122 points for two counts of a life felony, whereas the primary offense at conviction was a single offense of armed robbery, a first degree felony punishable by life, which yielded a point score of only 82, a 40-point error.1 Under a corrected scoresheet, appellant’s point score would have placed appellant’s base range in a different cell. Although appellant’s 15-year sentence imposed upon revocation of probation is within the permitted range under the guidelines, we have previously held that a facial error resulting in an increase of one or more cells requires reversal for resentencing, even in the absence of a contemporaneous objection. Haas v. State, 625 So.2d 103 (Fla. 1st DCA 1993); Sellers v. State, 578 So.2d 339 (Fla. 1st DCA 1991) (citing Higgs v. State, 470 So.2d 75, 76 (Fla. 3d DCA 1985), approved, 586 So.2d 340 (Fla.1991)).
A second issue raised by appellant is that the trial court erred in failing to enter a written order of probation. On remand, as the state concedes, the trial court is required to enter a written order of probation. -
