help with a template .dwt file

[sparksstud]

I'm having problems getting rid of this navigation.. I'm trying to update the links below with [code]<a href="products.php?cat=8"><img src=" "></a>[/code] but the only way I can edit this is going through a .dwt file which when I update it to the site, it doesn't change.
[code]<tr valign="bottom">
          <td width="204" height="20"><p class="head">BROWSE</td>
        </tr>
        <tr>
          <td height="164" align="left" valign="top"><div id="Navigation">
              <ul>
                <li><a href="products.php?cat=8" id="aQuickies"> DVDS</a></li>
                <li><a href="products.php?cat=9" id="aHuge">DVDS</a></li>
                <li><a href="products.php?cat=7" id="aThick"> DVDS</a></li>
                <li><a href="products.php?cat=6" id="aYoung"> DVDS</a></li>
                <li><a href="products.php?cat=1" id="aHuge"> DVDS</a></li>
                <li><a href="products.php?cat=2" id="aWell"> DVDS</a></li>
                <li><a href="products.php?cat=3" id="aMega"> DVDS</a></li>
              </ul>
          </div></td>[/code]

I have also found this code the collabrate with the code.
[code]<body<?php
if(@$_GET['cat']=='8')
echo" bgcolor='#F0F0F0' class='aQuickies'";
elseif(@$_GET['cat']=='9')
echo" bgcolor='#F0F0F0' class='aHuge'";
elseif(@$_GET['cat']=='7')
echo" bgcolor='#F0F0F0' class='aThick'";
elseif(@$_GET['cat']=='6')
echo" bgcolor='#F0F0F0' class='aYoung'";
elseif(@$_GET['cat']=='1')
echo" bgcolor='#F0F0F0' class='aHuge'";
elseif(@$_GET['cat']=='2')
echo" bgcolor='#F0F0F0' class='aWell'";
elseif(@$_GET['cat']=='3')
echo" bgcolor='#F0F0F0' class='aMega'";


?>>[/code]

all in all, when I edit this template file .dwt it won't update the site.

Any suggestions?  I hope this makes sense lol
