I am running Crystal Reports 9 and I am pretty new to this software. I am teaching myself with books, but I cannot seem to find an answer to my problem. I have a report with multiple drilldowns, retrieving its data from a sql backend. I need the users to be prompted for a date range based off of the RecvdDate field. I set up a parameter field with ranged dates, but when I open selection expert, I cannot seem to find how to choose thise parameter field. Any help would be greatly appreciated.
