I'm having a problem with a javascript function. It's made to add file fields dynamically to a small table. However, it works on firefox, but not internet explorer. In some of my changes trying to get it working, I my have fudged the remove function a bit.

Thank you for any help!

		<table class="sub_table" style="display: none;" cellspacing="0" id="comic_images">
          <tr id="comic_upload">
