That's confusing. There's no way to get "Spock" from the code. You only get the number in the value attribute. If the user were to choose Spock and McCoy, then you'd have: $_POST['ineeddatacaptain'][0] --> 2 $_POST['ineeddatacaptain'][1] --> 4 It's up to the programmer to associate 2 with Spock, and 4 with McCoy. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
