Render does not get called if Print When logic returns .f. Check all the Render methods in the hierarchy of the Report Listener you're using and make sure that any Render methods with code have a DODEFAULT(). For that matter, if you've added ANY code in ANY method of your Report Listener, make sure it has DODEFAULT() code.
