I'd suggest the use of addFormRule(). See the documentation http://pear.php.net/manual/en/package.html.html-quickform.html-quickform.add formrule.php There is another way that involves addRule(array(A, B), ...) and your own callback but it's more tricky and we haven't written the docs for that yet. Your case would make a good example... Feel free to investigate this too. Bertrand Mansion Mamasam
