To detect a change of the select list, you would have to use Javascript. If there's something that absolutely has to be executed on the server-side from this change (like an email, or database update) then you could make an Ajax request to a PHP script. However, you've not said what it is you want to do, only how to do what you think you should, which are not the same things. If you explain in more detail what you're trying to achieve, then we could offer better help. -- Thanks, Ash http://www.ashleysheridan.co.uk -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
