Terry....Originally I made the mistake of selecting "shipping not required" and I got this code:
<input type="hidden" name="no_shipping" value="2">
Then, after some studying of the PP manual; I found that the "2" code does mean "buyer must provide shipping address. However, I put thru a test (actual), purchase on my card and it never ask for my shipping address! Instead, it listed my billing address as the shipping address, with the link named "change" listed just under my billing address. (They never presented me with a shipping address form or ask me if my billing address was the same as my shipping address. In this case it was, BUT what if it wasn't? I would be upset with the seller when my purchase didn't arrive in a reasonable time!

Since reading about the security issues with the PP buttons; I'm a little skiddish about posting the entire button code, but really do appreciate the help you are offering.
