On Motion for Rehearing.
In the motion for rehearing, appellants raise an equal protection argument for the first time. Since this argument was not raised previously in their enumeration of errors, we do not have jurisdiction to consider it on rehearing. Sanders v. Hughes, 183 Ga. App. 601 (4) (359 SE2d 396) (1987).
Motion for rehearing denied.
