I've created a report that includes an On-Demand subreport. The report works fine in preview mode but when run on the server it is prompting for a value of the subreports parameter. If I don't specify a value, the subreport link does not display for any records. The parameter was setup automatically when I specified the subreport link on the main report and is used in the filtering of the subreport. Also note that I am passing in the resultsets to be used for the main and subreports.
