I am trying to build a subreport off of my main report. I am trying to link my subreport stored procedure to my main reports stored procedure. All of the paremeters on the sub report SP are of the same data type of the fields I am linking my parameters to in the main report SP. After I set it all up and go to preview it I get a "Not Supported" error box that pops up. Then I click ok and all i have is a blank white page. Does anyone know what is not supported? This happens when trying to build this report in crystal 2008. I even tried building this same report in crystal 10 and it works perfect. I don't know what I am doing wrong in the crystal 2008 environment. Please help
