The <form> tag of my overlay disapear as it loads, and the submit button doesn't work of course - submit

Question

I am using bPopup to load a form in an overlay. The form is basically in a that is loaded hidden in the page, and by clicking a button on the page, the overlay shows up on top with the form in it.
I was using this code in another page before and it worked fine but wanted to go the overlay route as I felt the user experience was better.
So what happens is:
The overlay loads perfectly, all fields are visible, but the submit button doesn't do anything.
Using firebug, I looked at the code of the overlay and realized that my opening and closing tags are gone from the div.
I check and they are present in the when hidden.. so I'm guessing something happens with bPopup as I load the overlay.
I couldn't find anything in the regard and turn to the community.
Thanks
here is a sample of the code:
The div in the page I load:
<div id="fileuploadbox">
<div id="fileupload_div" class="contentcontainer">
<div class="headings alt">
<h2>Upload a file</h2>
</div>
<div class="contentbox">
<form action="**mycontroller**" method="post" enctype="multipart/form-data">
<p><span class='label'>File:</span><input type="file" name="file" value="" id="uploader" size="34" /></p>
<p><span class='label'>Description:</span><input type="text" name="description" value="" id="smallbox2" class="inputbox" maxlength="250" /></p>
<p><span class='label'> </span><input type="submit" name="" value="Upload file" class="btn" />
</form>
</div> <!-- content box -->
</div> <!-- contentcontainer -->
</div> <!-- fileuploadbox -->
The Button it self:
<a href="#" class="fileuploadpop">
<div id="fileuploadpop">
Upload a file
</div>
</a>
The Javascript:
<script language="javascript">
$(document).ready(function(){
$("a.fileuploadpop").bind('click', function(){
$("#fileuploadbox").bPopup();
return false
});
});
</script>

The code you provided works fine in my mac Firefox and Chrome with bPopup. The submit button works!
May be something to do with your btn class which I have not defined or you might try putting this in a bare-bone page to test with bPopup first to track and resolve any other conflict.
