Can someone please tell me why I continually get this JavaScript error with IE8. The page loads correctly but it always shows this error:

Here is the code from my site:

-->
</style>
 
<script type="text/javascript"><![CDATA[//><!--
sfHover = function() {
	if (!document.getElementsByTagName) return false;
	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"), "");
		}
	}
 
}
