Working in FireFox not IE

Hi i have an Ajax script which is working in FireFox but not IE, obviosuly i want a wide range of people to be able to view, but cant seem to figure it out. Any help would be great, here is the code:

Code:

---

        function LocationClick(e){
                  if(e.elementID != null){
                        shape = map.GetShapeByID(e.elementID);
                        country = shape.GetID()
                        if(country == "msftve_1001_200000")
                                country = "AUSTRALIA";
                                ..........
                                else if (country == "msftve_1001_200017")
                                country = "BRAZIL";
                        getCountry();
                        }
                  }


                                function getCountry() {
                xhr = new XMLHttpRequest();
                submission = "id="+ country;
                  xhr.open("GET", "tickets.php?" + submission);
                  xhr.onreadystatechange = processNameData;
                  xhr.send(null);
            }


                function processNameData() {
                if (xhr.readyState == 4) {
                        var data = xhr.responseText;
                        document.getElementById("ajaxTickets").innerHTML = xhr.responseText;
                        }
                else {
                        document.getElementById("ajaxTickets").innerHTML = '<img src="images/loading.gif">';
                        }
                }

Now in IE the loading picture works, but the information is never loaded. Any help would be great

XMLHttpRequest() is for Safari and Firefox (and other browsers). For IE you need either Msxml2.XMLHTTP or Microsoft.XMLHTTP. The following try...catch will work for all modern browsers.

Code:

---

var xhr;
try {xhr = new XMLHttpRequest();}
catch(e) {
  try {xhr = new ActiveXObject("Msxml2.XMLHTTP");}
  catch(e) {
    try {xhr = new ActiveXObject("Microsoft.XMLHTTP");}
    catch(e) {
      alert("Your browser does not support AJAX!");
      return false;
    }
  }
}

thanks, worked a treat!
