Drill Through - Use Parameter Passed From Source As The Default In The Target Pr

[MegaCogman]

Using a drill through from 1 Source report to a single target report,
I am trying to get the parameter passed from my Source report to appear as the default on the Prompt drop down list of my target report.

I am passing P_Company parameter from source and receiving it on the target. I can get the target report to show the correct detail for the P_Company being passed, But I want the drop down list prompt on the target report to reflect the P_Company that is being passed as the default.

Thanks for any help you can Provide !
