[Crystal Rep] Passing parameter from subreport to mainreport

[madcrow74]

I have a mainreport which contains a subreport.
The subreport contains a field which i need to pass the value to the mainreport.
How can I do? Have I to use parameters?
Examples welcome :-D

right click on subreport and go to change subreport links. There the parameters can be setup.

This is to pass data from a main report to the subreport.... I want to make the opposite... or is it valid for both ways? :-O

why do you need the data in the main report, what are you trying to do exactly
