Question : JavaScript Error in IE7 menu hover background does not work

@ http://lab.doede.net/d3/ The hover effect (white rectangle showing up behind link onhover) in the menu does not work in IE7. There is a JavaScript Error:
Webpage error details

Message: 'document.getElementById(...)' is null or not an object
Line: 24
Char: 21
Code: 0
URI: http://lab.doede.net/d3/

and it is related to this piece of code in the header I have attached.

Any ideas how I can solve this error and make the menu function properly like it does in IE8 and Firefox as well as Safari?

         
          <!--[if lte IE 7]>
    <script type="text/javascript">
    sfHover=function(){var sfEls=document.getElementById("nav").getElementsByTagName("LI");for(var i=0;i<sfEls.length;i++){sfEls[i].onmouseover=function(){this.className+=" sfhover";}
    sfEls[i].onmouseout=function(){this.className=this.className.replace(new RegExp(" sfhover\\b"),"");}}}
    if (window.attachEvent)window.attachEvent("onload",sfHover);
    </script>
    <![endif]-->

Hey,
Looks like you just had the wrong id on line 24 as id nav does not exist it's navigation.
All the best,
Ian
