Problem with uploadify jQuery and javascript

[AnthonyM]

So I'm using uploadify to upload multiple images to a folder. Along with each upload, I want to pass along a 'batch name' from a text box value.When I hard code the batch_name (Fire) below, the database updates fine, but when I replace 'fire' with $('#batch_name').val() the value doesn't seem to pass.javascript\[code\]<script type="text/javascript">$(document).ready(function() { $("#uploadify").uploadify({ 'uploader' : 'uploadify/uploadify.swf', 'script' : 'uploadify.php', 'scriptData' : {'session_id': '<?php echo session_id(); ?>', 'batch_name': 'Fire'}, 'cancelImg' : 'cancel.png', 'queueID' : 'fileQueue', 'auto' : false, 'multi' : true });});</script>\[/code\]textbox\[code\]<input type="text" name="batch_name" id="batch_name"/>\[/code\]
