Can't find code in template

[HypedGaming]

I have a piece of code that is causing a problem on my forums (well, at least I think it is causing it):

</div></div></div></td></tr><tr><td class="cat_bottom" style="margin: 0px; padding: 0px; line-height: 0px;" colspan="5"><img src="http://cod4boards.com/clear.gif" alt="" height="8" width="1"></td></tr>
</tbody>
</table>

What it looks like on my forum: http://cod4boards.com/index.php?styleid=4
What it should look like: http://www.vbstyles.com/demo/?styleid=39

Note how the div/table ends right under the welcome message on my forum, and there is no background for the rest of the container.

Does anyone know where this code could be coming from? (and where to find it)

Also, this only happens on the index, the other pages show up as they should

Sorry if this is in the wrong section
