I cannot for the life of work out how to get the parameter for the sub report showing up in the master report.
The Job is in context and appearing in the report header but the contacts are not showing up in the detail. In the master report in the element properties for the subreport the 'Parameters for sub-report' is greyed out.
I have noted that the query in the subreport standing alone, does not stay in synch with the query in the subreport inserted in the master report. Generally, if you change the query in the subreport, it does not translate over to the embedded report. So change it by editing the embedded subreport. Might be the issue.
