>I believe that relying on Variables to calculate the totals in a two-band report is not a good practice. I found another report in my program, also two-band. And in that other report I was creating a Totals cursor (basically calculating the totals "manually" instead of relying on the Variables. I will do the same in this report.

You can always sum on a condition. This is Value to storecould be a condition like

iif(lExpression, nField, 0)

From help:
Value to store
Specifies an expression that is used to determine the value of the report variable during a report run. The report engine evaluates this expression each time it moves the record pointer as it processes the records in the current scope. Clicking the ellipsis (…) button opens the Expression Builder so you can build an expression. For more information, see Expression Builder Dialog Box.

I just like to tell you that too many report variables will slow down the report. Also the ORDER of the variables determine the ORDER they are processed. If you use one variable in the other. ;)
