Replicating DIV data in a TEXTAREA

[SpeedStreet]

Ok, I am working on a new hack, that needs one teensy little piece finished before I can release it to the world. The only problem is that the WYSIWYG editor isn't really a TEXTAREA; it's a DIV.

I was told that the best way to go about fixing this problem is to replicate the data in the WYSIWYG editor into a hidden textarea. This will solve the problem, and allow my script to execute properly.

That being said, I have the following code that is not working. I'm hoping someone can take a looksy and help figure out how to complete this snippet so that it will work properly.

Reward will be in the form of a contributor recognition when I release the hack later this evening.

PHP Code:

<!-- This is the existing WYSIWYG code from vB3 -->
<!-- I added the id="message" because I was told to -->
<!-- BEGIN vBCODE -->
<div class="controlbar" id="message">
<textarea name="message" id="qr_message" class="bginput" style="width:600px; height:100px;" rows="5" cols="60" tabindex="1"></textarea>
<!-- End vBCode -->

<!-- Here is the snippet provided to me -->
<!-- BEGIN SNIPPET -->
<textarea style='display: none' id='message'></textarea>
<script>
document.getElementsById('message').value = div.InnerHTML;
</script>
<!-- END SNIPPET -->

<!-- BEGIN vBCODE -->        
    </div>
<!-- END vBCODE
