2 forms, same page, 1st is file upload - works in IE, 'dies' in non-IE browsers

Hello, Banging my head against this one... Briefly: - I have two forms on the same page - both forms are: action="<?php print $_SERVER['PHP_SELF']; ?>" method="post" - both forms gave unique ids - both forms have a hidden file of the type <input type="hidden" name="_add_new_module_details" value="1" /> which is checked directly below the form with an "if(array_key_exists('_add_new_module_details', $_POST)) { ...}" method - first form is a file upload - 2nd form is a details submit - submit button on 2nd form is only 'turned on' (via AJAX) once the user has uploaded file file - 2nd form validated fields contents, via an onsubmit - after 2nd form successuly submitted, head off back to another page In Internet Destroyer, the page works just fine (i.e., both forms fire as expected) In the non-IE browsers I have tried (Firefox, Chrome, Opera), the first form uploads the file properly, the 2nd form's submit is 'turned on' by AJAX - BUT the submit button on the 2nd form doesn't seem to do anything - i.e., the onsubmit is not being triggered, etc, etc help! <smile> Thanks in advance: GREG
