Design problem!!!

[Markus Hain]

In meinem Script wird die höhe der spalte an dem von mir markierten  Beriech beliebig verändert, obwohl diese fest vergeben wurde.

Hoffe auf tipps

Hier mein Script

<table width="100%" height="100%" border="0" cellspacing="0" cellpadding="0" bgcolor="#A48D79" bordercolor="#000000">
<tr>
<td height="169" colspan="3" valign="top" bgcolor="#A48D79" style="background-image: url(../img/banner_new.jpg); background-position: left; background-repeat: no-repeat; background-color: #A48D79;"><img src="../img/banner_new_text.jpg" alt="" border="0" usemap="#admin"><img src="../img/nix.gif" alt="" width="40" height="1" border="0"><map name="admin"><area alt="" shape="circle" coords="185,57,3" href="../memberonly/memberonly.php"></td>
