I'm assuming you've got something like this going on:

• Page One - hidden input field with JUMP URL in it
• Page Two - reads hidden input field, creates continue link
• Page Three - attempts to read hidden input field, doesn't find it, creates empty continue link

The reason you're not getting the link on page three is that to pass the url value from Two to Three, you'd need a form on Page Two with the same hidden input field, and the 'Continue' link would have to submit the form for the value to be available on the next page.

What I'm trying to say is, the form values are only present on page Two - page Three has no knowledge of them.

I suggest you look at the CGI material in the Tutorials section!
