Looking at your source view I see..
<tr>
<td width="100" bgcolor="#0068CF">
<a href="http://www.teentoday.co.uk/gossip/" class="menulink" class="&{ns4class};">
Celeb Goss</a></td>
</tr>
<tr>
<td width="100" bgcolor="#0068CF">

<tr>
<td width="100" bgcolor="#0068CF">
<a href="http://www.teentoday.co.uk/shop/" class="menulink" class="&{ns4class};">
Shop</a></td>

notice the class="&{ns4class};" instead of class names? Not to mention the double tags
class="menulink" class="&{ns4class};"
This is not proper css syntax
