help regarding container for forum

[forrie]

g'day all i'm having a little trouble getting a border that contains the forum in it to show up at all times when browsing through the forum.

the style sheet can be found here www.laventrix.com/style.css

here's the header code

 
 <div id="container">
<div id="header">
<!-- include a header image -->
 
</div>
 
$menu
 
<div id="content">

<div class="corona">
<b class="top"><b class="b1"></b><b class="b2"></b><b class="b3"></b><b class="b4"></b><b class="b5"></b></b>
<div class="float-right">
<br />
        $message
 <if condition="$vbphrase[unread_x_nav_compiled] != 'Unread 0'">
<if condition="$show['pmstats']">
<br /> <br /><ul><strong> <a href = "$session[sessionurl_q]private.php"><font size="4" color="red" >Private Messages:$vbphrase[unread_x_nav_compiled]</font></a></strong></ul>
</if>
</if>
<br />
<br />
</div>
 
<div class="boxcontent">

the footer code ( only relative parts )

 
    <if condition="$vboptions[privacyurl]"><a href="$vboptions[privacyurl]">$vbphrase[privacy_statement]</a> -</if>
    <a href="#top" onclick="self.scrollTo(0, 0); return false;">$vbphrase[top]</a>
   </strong>
  </div>
 </td>
</tr>
<tr>
<td>
<!---->
</div>
<b class="bottom"><b class="b5"></b><b class="b4"></b><b class="b3"></b><b class="b2"></b><b class="b1"></b></b>
</div>
</div>
<!---->
</td>
</tr>
</table>
<div id="copyright">
<!---->
<!-- and-->

</form>
<!---->
</div>
</div>
<!---->
<if condition="$show['dst_correction']">
<!-- auto DST correction code -->
<form action="profile.php?do=dst" method="post" name="dstform">
 <input type="hidden" name="s" value="$session[sessionhash]" />
 <input type="hidden" name="do" value="dst" />
</form>

the problem is when i go to view a thread it looks like this
www.laventrix.com/images/123/problem (640 x 512).jpg

when it should have a container like this
www.laventrix.com/images/123/ok (488 x 645).jpg

any ideas

cheers
