Thanks synapse...
Pathing to the file will open the subreport in Crystal Reports in design time. I meant to say "how can I run the on-demand subreport through a hyperlink?".
I'm going a different route, though. What I'm going to do is create a link to a .net webform which will display the report based on parameter values from the QueryString. I'm actually in the process of doing that right now, and I'll see how that turns out.
Thanks again.
