I'm attempting to create a variable that will allow me to perform some calculations on it later, but I want to zero out this variable at the beginning of each group. Where do I need to place my formula to zero out the variable? I tried this in the suppress section of the group:

whileprintingrecords;
numbervar linenumber:=0;

But it keeps telling me that my result must be boolean. I'm using CE 8.5.

Thanks,

Chris

Create a formula (Insert->Field Object->Right click formulas and select new).

Then place the formula in the group header.

To increment it, create another formula in the details section:

whileprintingrecords;
numbervar linenumber:=linenumber+1

To display the results at the group footer, use another formula:

whileprintingrecords;
numbervar linenumber
