Can anyone see whats the problem with this code?

<script type="text/javascript">
var xmlHttp;
function stateChanged() { 
	if (xmlHttp.readyState==4) { 
		document.getElementById("mysql_check").innerHTML=xmlHttp.responseText;
	}
}
function getXmlHttpObject() {
	var xmlHttp = null;
	if (window.ActiveXObject) {
  		xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
 	} else if (window.XMLHttpRequest) {
  		xmlHttp = new XMLHttpRequest();
 	}
	return xmlHttp;
}
function mysqlReset() {
	document.getElementById("mysql_check").innerHTML = "<input type=\"button\" value=\"Check Connection\" onClick=\"mysqlCheck()\">"
}
function mysqlCheck() {
	document.getElementById("mysql_check").innerHTML = "Checking...";
	var host = document.getElementById("mysql_host").value;
	var user = document.getElementById("mysql_user").value;
	var pass = document.getElementById("mysql_pass").value;
	var db = document.getElementById("mysql_db").value;
	if (host.length==0 || user.length==0 || pass.length==0 || db.length==0) {
		alert("Please fill in all fields");
		mysqlReset();
		return;
	}
	xmlHttp = getXmlHttpObject;
	if (xmlHttp==null) {
		alert("Your browser doesn't suppert AJAX which is needed to check your connection");
		mysqlReset();
		return;
	}
	var url = "http://www.stuff4web.co.uk/SCMS/admin_check_mysql.php?h="+host+"&u="+user+"&p="+pass+"&d="+db+"&s="+Math.random()*10;
	xmlHttp.onreadystatechange = stateChanged;
	xmlHttp.open("GET",url,true);          // LINE 74
	xmlHttp.send(null);
}
</script>
