I am very new at creating Crystal Reports and am using Crystal 10.  I have created a simple report and inserted a subreport.  Now I would like to be able to create a formula in my report that adds a number from my subreport and original report.

I have tried using the following formula in my subreport:

WhilePrintingRecords:
Shared CurrencyVar :=GroupName ({CNA_ACTIVE__CONTRACT_DERIVED.Contract})

But I get an error that highlights the equals sign and says "A statement is expected here"

Any ideas as to what I am doing wrong in the subreport and what formula I need to add to my main report before I can create the addition formula?
