generatePDFOutput with a variable form.

Hi

I have a process which uses generatePDFOutput2 to produce a PDF.  This works fine at the moment, but I need to pick the form based on a variable value which is passed in.

I've tried every combination of including the application name or not, with and wtihtout the version number, using forward slashes or backslashes and including the .xdp extension or not, but nothing seems to work.  The document I can find seems to be pretty vague on what I should put in.

Can anyone help?

For reference, the path of my form as viewd in the Applications tree is of the structure: APPNAME/APPNAME/1.0/Subfolder/Formname

When I use a literal value for the Form in generatePDFOutput2 is: URI = Subfolder/Formname.xdp, Created 6/12/10

Thanks

Dan
