Hi,

I want to add sum numbers in crystal report.

see it example of general ledger.                                                                

                                                                            debit           credit     balance

account no.     1234         opening balance                                           123

           transaction 1                                         1232          

           transaction 2                                                             -345

                               period total                       1232             -345        887

                            closing balance                                                      1010

I can group sum the debit (1232) and credit (-345).

I want to know how to add the debit sum and credit sum  and add the opening balance (123) in crystal report. = 1010?
