concurring in the result only.
In the present case, significant portions of the trial court’s findings of fact numbered 49, 50, 52, 53 and 54, upon which its determination of a substantial change of circumstances is based, are unsupported by competent evidence of record. Accordingly, under our law the court’s order is defective and must be reversed. See Coble v. Coble, 300 N.C. 708, 714, 268 S.E.2d 185, 190 (1980). I therefore concur in the result reached in Judge Greene’s opinion.
