I got it !

Your problem is a missing closed tag in your TD where it says:

<TABLE align=center border=0 cellPadding=0 cellSpacing=0 width="100%" height="100%">
  <TR>
    <TD valign=top>
<TABLE align=center border=0 cellPadding=0 cellSpacing=0 class=HeadBox width=100%>  
<TR>
[b]<TD colspan="2" valign="top" align="center"[/b][img]../skin1/images/headbarbed.jpg[/img]<table border=0 cellpadding=0 cellspacing=0>
    <form method="get" action="../customer/search.php" name=productsearchform>

Notice the bold part, you didnt close your td tag properly before adding the:
[img]../skin1/images/headbarbed.jpg[/img]

Try that, it will probably solve your problem.
