transfer data from subreport to mainreport

i'm working with CR 8.5 and VB6.

I made up a Report with a subreport.
In the subreport i built an variable like this:

shared stringvar strFirstValue := cstr({dao.startzeit});

The formula is placed in the header section(either group or page header)  to get the first dataset from the detail Section.

I transfer this variable to the main report like this:

shared stringvar strFirstvalue;


Everything is working fine, when i put the formula in the footer sections of the main report.

Unfortunately i have to use this value in the page header section. There i get always an empty string.

How do i assign this variable to work in the Page header of the main report?

Thanks in advance

You cannot use the result of value from a subreport at an earlier point in the main report - the subreport must run first before any data from it can be used in the main report.

If you want a visible output from your subreport below the page header, then, in principle,  you need to create another version of your subreport that can be placed in the page header (and produce no visible output but set the shared variables as required) above the point you want to display the result.

However, without knowing more about the structure and main-subreport links I can't say for sure whether you can achieve that. And of course page headers only get created if there is something to put on the page.
