Passing Command Date Parameters to Subreport

[mwake]

I've got a commission report that has start and end date parameters in the command line. I created a subreport to track stocking fees for for each customer, since reps aren't paid commission on these fees. I added the subreport to the main report but I am unable to link the invoice date field in the subreport to the start and end date parameters in the main report. When I select the start date parameter in the subreport links box, I don't get any fields to link to it in the subreport. The subreport was not created with a command, so I tried creating the same report using the command line and added date parameters but still couldn't link them to the main report parameters. How do I pass date parameters from a command to a subreport?

I have done it several times without an issue. Not sure what is going on. The only thing that comes to mind is that the date parameters have to be the same data type (date-date or datetime-datetime).
