If i view the source I won't see any PHP code, and you said it was php causing the error.
It's an HTML problem, maybe try changing
<tr>
<td height="94" colspan="3" valign="top"><img src="/rpg/images/navtop.jpg" width="174" height="94"></td>
<td colspan="3" rowspan="3" valign="top" background="/rpg/images/content.jpg"><p>
to
<tr background="/rpg/images/content.jpg">
<td height="94" colspan="3" valign="top"><img src="/rpg/images/navtop.jpg" width="174" height="94"></td>
<td colspan="3" rowspan="3" valign="top"><p>
I haven't had a good look at how its all set out, and don't have the time to, maybe someone else can be more of a help:bemused:
