I think the problem is on the this page.

 
 
   language = "javascript" type = "text/javascript">
     //Browser Support Code
     function ajaxFunction() {
        var ajaxRequest;

        try {        
           // Opera 8.0+, Firefox, Safari
           ajaxRequest = new XMLHttpRequest();
        } catch (e) {

           // Internet Explorer Browsers
           try {
              ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
           } catch (e) {

              try {
                 ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
              } catch (e) {
                 // Something went wrong
                 alert("Your browser broke!");
                 return false;
              }
           }
        }

        // Create a function that will receive data
        // sent from the server and will update
        // div section in the same page.
        ajaxRequest.onreadystatechange = function() {

           if(ajaxRequest.readyState == 4) {
              var ajaxDisplay = document.getElementById('ajaxDiv');
              ajaxDisplay.innerHTML = ajaxRequest.responseText;
           }
        }

        // Now get the value from user and pass it to
        // server script.
        var age = document.getElementById('age').value;
        var wpm = document.getElementById('wpm').value;
        var sex = document.getElementById('sex').value;
        var queryString = "&age = " + age ;

        queryString +=  "&wpm = " + wpm + "&sex = " + sex;
        ajaxRequest.open("GET", "http://localhost/ajax-example.php" + 
  queryString, true);
        ajaxRequest.send();
     }
