Sub-Report - Repeated input parameter prompt.

I have 2 sub reports in detail section of the main report. They all have the same i/p parameter(date) and i have linked the i/p param of the main report with the sub report thro the change links of the sub-report command. The problem is once i run the report it prompts for the i/p again and again.....
Does anyody have a solution to this problem


thanks in advance

Check your selection formulas in the subreports. For some reason it looks like the subreports are not actually getting the parameter, and I usually find that the selection formula got messed up. Another reason could be that the link could be used in another formula somewhere, and then was changed. I had this happen once, after setting up all of the formulas on the subreport, I changed the parameter name. The formulas however did not automatically change the parameter name. Finally, recheck that the links to the subreports, just in case.
