Change it to this, also your missing the top part of the table tag, make sure you put it back in there before saving.
Code:
cellspacing="0" align="center">
<tr>
<td align="left"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>
<td align="right">
$banner
</td>
</tr>
</table>
<!-- /logo -->
<!-- content table -->
$spacer_open
