Unanswered: Use subreport value in the formula of the main report
How can I use the value or field in my subreport to a formula in my main report? I was able to display the value of the subreport in the main report, but i also want to use that value in a formula? How can i do this.
Basically you need to use a variable that is "shared" between the main report and the sub-report. Have a look in the help files about shared variables to get some background but to summarise, the value a variable holds at the point you leave the subreport is then available in the main report in the same section.
