Navigation bar IE6 dropdown not displaying

[surfsup]

Failry simple navigation bar created buthaving issues in that it does not show in IE6

 

Look at www.villasites.com in FF the about option has a dropdown... not in IE6 but no error showing

 

Here is nav bar code

 

<ul id="navbar">
<li><a href="#"><img src="images/about_top.gif" alt="about" width="85" height="11" border="0" /></a><ul>
  <li><a href="index.php">Home</a></li>
  <li><a href="whatwedo.php">What We Do</a></li>
  <li><a href="packages.php">Packages</a></li>
    <li><a href="gobespoke.php">Go Bespoke</a></li>
      <li><a href="whoarewe.php">Who Are We</a></li></ul></li>
  <li><a href="examples.php"><img src="images/examples.gif" alt="examples" width="110" height="11" border="0" /></a></li>
  <li><a href="prices.php"><img src="images/prices.gif" alt="prices" width="84" height="11" border="0" /></a></li>
  <li><a href="contact.php"><img src="images/contact.gif" alt="contact" width="94" height="11" border="0" /></a></li>
</li>
</ul>

 

and this is relevant CSS

 

#navbar {
    margin: 0;
    padding: 0;
    height: 1em; }
#navbar li {
    list-style: none;
    float: left; 

}
#navbar li a {
    display: block;
    padding: 0px 0px;
    background-color: #5e8ce9;
    color: #fff;
    text-decoration: none; 

}

#navbar li ul {
display: none;
width: 8em; /* Width to help Opera out */
background-color: #BEE1E1;
font-family: Georgia, "Times New Roman", Times, serif;
font-size: 12px;
color: #666;

}
#navbar li:hover ul {
display: block;
position: absolute;
margin: 0;
padding: 5px;
}
#navbar li:hover li {
    float: none; }
#navbar li:hover li a {
background-color: #BEE1E1;
border-bottom: 1px solid #fff;
color: #000;
padding: 5;
}
#navbar li li a:hover {
    background-color: #8db3ff; }
