Can a SubReport pass a Value back to the main report? 1

[DavidKnight]

I use subreports quite extensively, linking from my main report to sub's. And that works well sending(Linking) values to the subreport.

But how do I return a value, such as number of rows read/displayed, back to the main report?

This is Crystal Reports 9.0!

Hi David,
you can declare a variable in the subreport via a formula such as :

shared stringvar MyText:=whatever value you want it to have;

Then in the main report you have another formula such as :

shared stringvar MyText;
MyText;

Which will be populated after the subreport has run. Be careful of where you put the variable in the main report as the subreport MUST run first so don't place the main formula in the report header and the subreport in the report footer.

Hope this helps.

Note that a value from a subreport will not be available until the section after the section containing the subreport.
