My way of getting around this has been to put the data manipulation into a "process" page, which redirects back to the content page when its finished processing. That way, when the user hits refresh it doesn't ask to resubmit the data. It just refreshes the display. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
