The JD

What I have is a report using Reporting Services 2005 that will take in a parameter through the URL called RepID, so the parameter is hidden inside the report because it's passed through the URL. This will run the report for the specified Rep. However, I'd like to have another paramater (Or also using RepID) just as Admin which would be a boolean and when Admin='N', the RepID parameter should not be displayed on the screen and just be accepted through the URL paramater RepID. However if Admin='Y' is the URL paramater passed, I want the RepID parameter to be displayed in the report so that the Admin can enter whatever RepID they want to run the report. Is there anyway to do this without creating a separate Admin version of the report
