Forum Main body width wont change!

[mrconfus3d]

Im a bit confused. Can you show me what i would have to edit?
Code is:

<!-- logo -->
<a name="top"></a>
<br style="display: none;">
<table class="bordercolor" align="center" bgcolor="#000" border="0" cellpadding="0" cellspacing="0" width="$stylevar[outertablewidth]">
<tbody><tr>
<td width="100%">
<table border="0" cellpadding="0" cellspacing="0" width="100%">
<tbody><tr>
<td width="100%" height="100%" align="center"><font size="+1"><a href="http://www.clansgfh.com/forum/index.php"><img src="http://www.clansgfh.com/forum/images/clansgfh/clanlogo.gif" border="0"></a></font>
</td>
</tr>
</tbody></table>
</td>
</tr>
</td>
<!-- /logo -->

Ok. So for a temporary fix i just copy pasted the old code in and edited a bit. It looked great...until i got to the cmps page. The center column of modules keeps expanding the page and it looks terrible. I looked under style options but there was nothing to fix this. How would i fix this?
