When I removed this script from my site, the "Object Required" Error on Page message disappeared. IE says the error is on line 5, char 11... but that doesn't make sense to me. any pointers??

If it helps, this code was something i found to help a CSS dropdown menu function properly.

startList = function() {
if (document.all&&document.getElementById) {
navRoot = document.getElementById("ulnav");
for (i=0; i<navRoot.childNodes.length; i++) {
node = navRoot.childNodes[i];
if (node.nodeName=="LI") {
node.onmouseover=function() {
this.className+=" over";
  node.onmouseout=function() {
  this.className=this.className.replace(" over", "");
