We affirm the order of the trial court revoking appellant’s probation, but we remand this case for resentencing of appellant. The present sentence does not specifically set forth the period of credit time appellant is to receive as Section 921.161(1), Florida Statutes (1975) requires. Smith v. State, 310 So.2d 770 (Fla.2d DCA 1975). Appellant need not be present at resentencing.
