Unfortunately, because these calculations vary greatly on several factors... it would be next to impossible to put them in the small EXPRESSION field in the report writer itself. In addition, trying to store them in temporary variables during the actual criteria step of the report call would be nearly impossible as well... to many factors control what needs to be calculated.

Anyway and yet another wrong path? The function still would return its caculation result and would not be called from OnEntry() :) Just put it where it should be displayed.
