Showthread problem with side bar in header
 

Please help - I messed up my header template and lost some of the side bar coding.

the sidebar is back, but...

I started it with:
<table border="1" cellpadding="0" cellspacing="0" width="100%">
<tr>

<td width="13%" valign="top" bgcolor="#cccccc"><font size="2" color="#880000" face="Arial">

and I have ended the header template with:

</td>
<td valign="top">

so that forumhome etc will start at the top of the page regardless of how long the sidebar is and how short the forum home is. It work except for showthread...

When I look at a thread (showthread) the navbar comes up ok at the top, but the post itself way below the sidebar.
