validation loop and back button, and wont wear a wig !!

Which back button are you referring to? One you've added, or the browsers back button? If you're talking about the browsers back button, it won't work for two reasons:

1) Unless you redirect after each form submission, you'll end up with the user submitted data more than once without doing it intentionally. Also, they will see an annoying popup asking them if they're sure they want to resubmit the form.
2) Cache. As far as I'm aware, your browser will call on a cached page when you use the back button.

However, this is your solution in a way. If you're adding your own custom back and next buttons, the value attribute for those buttons can be set to the appropriate page number, so that you app knows which page the user is currently on.

Hope this helps.
