I gather that all of the script occurs on one page, and that the page is 'refreshed' by some action of the user (i.e. that the user has clicked/entered login info on some other page, and that this page then needs to detect that change.) What may be happening is that the refresh action triggers the script twice: once for the initial loading and again for the reset values. Hence, $ref_page gets reset by line 53 ($ref_page = get_ref_page(); I experienced the same difficulty once, and essentially solved the problem by adding an extra page that is called, by a simple switch statement, if there is a change: i.e, from 'community' to 'market'. Another question, by any chance, are you switching into https by any chance? Hth, Andre -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
