Data retrieval failed for the subreport, 'Subreport5', located at: C:...

Can you run the subreport by itself, given the right parameters? If you can't, your problem is that.

If you can run it successfully by itself, double-check that you are passing the parameters correctly to your subreport. Make sure the parameter types match and that you are passing all of them.

Another problem might be that -- if I recall correctly -- when you have a subreport in a local report, you need to provide the data for the subreport programmatically, just as you do with the parent report. There's an event that's raised - SubreportProcessingEvent -- when the subreport is being processed. You write a handler for that event and supply data in the handler. Here's some more information about it: LocalReport.SubReportProcessingEvent. There's a good example on that page.
