Ajax works on IE but not on Firefox - Newbie?

Tried to use ajax to show a string from html #2, but the code only works on IE and not on Firefox (nothing has came out, not even an error). The code is on a localhost (IIS). Below is the js code in the html #1 header.

%26lt;script type="text/javascript"%26gt;

function ajax_test() {

var obj = "test";

var server_page = "abc.htm"; //contains string only

var xmlhttp = false;

try {

//for javascript ver. %26gt; 5

xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");

} catch (e) {

//for older version

try {

xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

} catch (E) {

//for non IE browsers

xmlhttp = false;

}

}

if (!xmlhttp %26amp;%26amp; typeof XMLHttpRequest != "undefined") {

xmlhttp = new XMLHttpRequest();

}

xmlhttp.open("GET", server_page);

xmlhttp.onreadystatechange = function() {

if (xmlhttp.readystate == 4 %26amp;%26amp; xmlhttp.status == 200) {

document.getElementById(obj).innerHTML = xmlhttp.responseText;

}

}

xmlhttp.send(null);

}

%26lt;/script%26gt;

Plz help

It looks good... anyway I'll change this fragment:

if (!xmlhttp %26amp;%26amp; window.XMLHttpRequest)

xmlhttp = new XMLHttpRequest();

When you are in these situations, try to put some alert('Debug message...') around, to be sure on what is really ran.
