Cumulative column

Hi,

I am trying to add a cumulative column in the masterdata.

For example,

+-------+--------+-------+---------+------------+
| DATE  | CREDIT | DEBIT | BALANCE | CUMULATIVE |
|-------+--------+-------+---------+------------+
| 10-10 |  0.00  | 10.0  |  10.0   |  10.0      |
| 10-10 |  0.00  | 10.0  |  10.0   |  20.0      |
| 10-10 |  0.00  |  5.0  |  10.0   |  25.0      | 
| 10-10 | 15.00  |  0.0  | -15.0   |  10.0      |
+-------+--------+-------+---------+------------+


Though, when I insert a running total sum, the field disappears. It only works with aggregate functions (for groups, not for lines).

Any thoughts? I know this option was available and very easy to use in QuickReports...

Thanks!

    Use script variable and calculate running total in the band's OnBeforePrint event

    var Total: extended;
procedure MasterData1OnBeforePrint(Sender: TfrxComponent);
begin
  Total := Total + <Customers."Cust No">
