The part that processes the form input would redirect back to itself after the data is inserted into the database, thus getting rid of the post data. So subsequent refreshes of the page will refresh without attempting to repost the data. The only other way to do it is to check the data you're about to insert to see if it's already there. If it is, then don't insert it... ---John W. Holmes... PHP Architect - A monthly magazine for PHP Professionals. Get your copy today. http://www.phparch.com/
