Css menu

ok well i’ve got this neat Css menu. And i would really like it to work with the catagory tag. But it doesn’t add any of the links but the first one which is ‘general’. If anyone has a idea that would be great.
Heres the code of the menu and css
——————-
Menu:
<div id="navigation">

<li id="currentpage">
<?php wp_list_cats(); ?>
• Login

</div>
——————-
Css:
#navigation ul {
list-style: none;
margin: 0;
padding: 0;
}
#navigation li {
background: #ccc;
border-left: 1px solid #999;
float: left;
margin: 0;
padding: 0;
}
#navigation a {
color: #666;
font-weight: bold;
padding: 5px 10px;
text-decoration: none;
}
#navigation a:hover {
color: #333;
}
#navigation #currentpage a {
background: #fff;
color: #333;
}
