Ul Menubar Positions Correctly in Firefox but NOT in IE

Question

Hi I am having problems with my ul menubar. It displays correctly in dreamweaver and firefox but not in IE 9. Below are screenshots of what im trying to achieve. I placed the ul menubar where i want it (horizontally dropping down rather than vertical) and made its position absolute but for some reason IE does not like this. If there is anyone out there who would be willing to help me i would me most grateful!! Im relatively competent with dreamweaver cs5.5. Much thanks!
Here is Firefox working properly:
Here is Internet Explorer not working properly:
Here is the menubar code:
  <td height="27" align="right" nowrap="nowrap"><ul id="MenuBar1" class="MenuBarHorizontal">
    <li><a class="MenuBarItemSubmenu" href="../html/index.html">links</a>
      </li>
    <li><a href="../html/portfolio.html">contact</a>      </li>    
    <li><a class="MenuBarItemSubmenu" href="../html/profile.html">profile</a></li>
    <li><a href="../html/contact.html" class="MenuBarItemSubmenu">projects</a>
      <ul>
        <li><a href="#">industrial</a></li>
        <li><a href="#">institutional</a></li>
        <li><a href="#">commercial</a></li>
        <li><a href="#">residential</a></li>
        <li><a href="#">award winning</a></li>
      </ul>
    </li>
    <li><a href="../html/links.html">home </a></li>
  </ul></td>
Here is the menubar script:

/* HACK FOR IE: to make sure the sub menus show above form controls, we underlay each submenu with an iframe */
ul.MenuBarHorizontal iframe

filter:alpha(opacity:0.1);
/* HACK FOR IE: to stabilize appearance of menu items; the slash in float is to keep IE 5.0 from parsing */
