Passing a parameter from main report SP to subreport SP

Hi,

I am using crystal reports 8.5

I have a report which has a subreport. The main report and the subreport are driven by two separate sybase SPs. The main report SP accepts 3 input parameters while the subreport SP accepts one.
One of the 3 input parameters of the main report SP is to be passed to the subreport SP as its input parameter.
So ideally when the report is run, it should ask for only 3 input params.

I tried to link the subreport. But somehow in the link box, I can't see the input parameter of the subreport which is what I want to link to the param of the main report.

Can anybody help ?

Thanks a lot,
AparnaYou can make use of Shared variables.
Assign parameter values to them and use them in subreports. Read it in help file
