Hi friends

I am new to this forum and new to crystal report.

My client is having crystal report 8. I copied a forumal from crystal report 11. Which was not working in crystal report 8. I am getting a error message as "The summary / running total field could not be created." I don't what it means and what I have to do? I paste my formulat bellow u all reference. Please help to solve the problem.

If {@Category Flag} = 1 And
(Sum ({@CurrentBalance}, {@Category Flag}) <> 0 Or
Sum ({@CurrentBalanceLY}, {@Category Flag}) <> 0 Or
Sum ({@CurrBalOneMonthAgo}, {@Category Flag}) <> 0) Then
"Current Assets"

Thanks in advance.
