SmartViewer and prompting for parameters

[Spuriousbugfix]

I have recently been looking at integrating crystal with ASP. I have been using the SmartViewer ActivreX
Everything seems to be okay when I pass the parameters to the report.
However I also need to run reports that have parameters which will prompt the user to enter them (as would happen if running them from Crystal itself).
So far I can't find out how to do this.
If I run a report that requires parameters and do not pass them in I get an empty report.
Any help with this would be appreciated.
I am using Crystal 9.

Thanks
