hi ...

could you post what you get from:

Expand|Select|Wrap|Line Numbers
  1. var firstCategory=XMLData.documentElement.firstChild;
may be there is a whitespace-problem in your xml-document? try to refer the first element another way ... through tagName or something like that.

kind regards

That is my HTML page:
[HTML]<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">
<script language="javascript" type="text/javascript">
function AJAX(num){
XMLObject = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
XMLObject = new XMLHttpRequest();
if (XMLObject.overrideMimeType) {
} else if (window.ActiveXObject){ // IE
try {
XMLObject = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
XMLObject = new ActiveXObject("Microsoft.XMLHTTP");
}catch (e) {

if (!XMLObject) {
alert('Cannot create XMLHTTP instance');
return false;
if(XMLObject.readyState==4 && XMLObject.status==200){
var XMLFILE=XMLObject.responseXML;
function makeList(XMLData,num){
var firstCategory=XMLData.documentElement.firstChild;
var AllMenus=firstCategory.getElementsByTagName("Menu" );
var firstMenu=AllMenus[num];
for(i=0;i<document.getElementById("Menu").options. length;i++){
document.getElementById("Menu").options[i]= null;
document.getElementById("Menu").options[i]=new Option(firstMenu.childNodes[i].firstChild.nodeValue);
function makeData(what){
return what.selectedIndex;
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<form id="form1" name="form1" method="p ost" action="">
<select name="Category" id="Category" onchange="AJAX(makeData(this))">

<option>Consumer Electronics</option>
<option>Jewelry &amp; Watches</option>
<option>Real Estate</option>
<select name="Menu" id="Menu" onchange="">
