Thanks guy's. I didn't think that was possible, but was worth trying.
The problem I have is on the first page a customer filles out a form, clicks submit. The submition to the DB happens on the next page. Then there is more stuff to fill out and click submit again, the info gets passed in and goes on to the 3rd paged. Here is where the problem is. If the customer presses the back button to the 2nd page, the call to submit the info is going to happend again.
How to avoid this and not have a bunch of variables going from page to page?
Thanks.
