Spawning Pages and Reader Extensions

I have a request form created in Acobat 8 Pro. A few of the items on the request form require a second form to be filled out, so I add javascripts to those fields that "spawn" that second form (and fills in the "duplicate data".

this.spawnPageFromTemplate("pagename");
this.pageNum++;

This works very well, but since I also must have a signature on each form, I enabled Reader Rights to the form and now it does not work.

So the question is:
Is there a better script that I can use that will work with Reader Extensions?
or
Do I need to create the form in Acrobat 9?
or
Am I stuck with trying to get my users to remember to go to the second form?

Thank you
