Outputting to a single page with RAS InteractiveViewer

Hi,  I'm attempting to output a report into one  HTML page using the CrystalReportsInteractiveViewer. I don't want to display the toolbar to allow users to navigate pages.  When I set the .IsSeparatePages property to false sometimes I get a 'Catastrophic Error'.  Setting the property back to true produces no errors but of course this outputs to HTML one page at a time.  Does anyone have any ideas how I can get the HTML to output to one page? Or why sometimes I get 'Catastrophic Errors' and sometimes I don't.  I've included my viewer code for your information.

I'm beginning to pull my hair out so any help would be appreciated.

Thanks,
