Sub Reports

Hi,

I have taken the Subreport. In the main report two groups are there based on ID(first group), timestamp(second group), for my purpose, i have taken subreport in the second group (it returns one value), based on the timestamp sometimes, it gives two values for one id. i want sum of these two values for one Id, i have used shared variables in the subreport, i am getting value back from the crystal report, can you give me any solution for this?

Regards

Pavani
