I don't even know what the formulas are since the report was created by someone else and I'm fairly novice about Crystal report, so I can't really figured out those formulas. But I did get some help from Seagate's Tech Help and they suggested a three formula approach. Below are the sample formulas that they gave me.
//goes in group header for dept, resets count to zero
WhilePrintingRecords ;
NumberVar DeptEmpCount := 0
//goes in the detail section, increments employee count
WhilePrintingRecords ;
NumberVar DeptEmpCount := DeptEmpCount + 1
//goes in the group footer for dept, shows dept emp count
WhilePrintingRecords ;
NumberVar DeptEmpCount
Thanks a lot for your help guys.
