Subreport Return Values

[planetzone]

Hi,

I have many subreports in the detail band of my main report. Each subreport returns a total value to the main report.

These values are stored in variables an the displayed in the same detail band as the subreports.

Now I want to calculate the difference between two of my returned subreport values. So I created a new variable which subtracts one subreport variable from the other. But only "null" is displayed when I execute the report.

The evaluation time of the displayed total variables is set to "Band" and of the variable to calculate with is set to "Report".

The "Reset type" for both variables is set to "None".

To eliminate the possibility of an error in my calculation, I tried to just display the value of the total variable in another variable.
But this also displayed "Null".

 

Does anyone has a suggestion on what could cause this?

 use evaluation time as  report

I tried almost every combination of evaluation times, but always with the same result.
