Firbug gives error "Ajax is not defined"
I have this HTML form which uses AJAX to pass data to a php file(did this so i dont have to leave the current page) Firebug gives me two errors 

        document.getElementById("name") is null
        ajaxget is not defined

The code is, i only started using AJAX today out of desperation,so i m very new to it.the php file is second.php, the important is that it receives the variables so it can create an output to be used by another html later, it doesnt have to respond back.Thank you in advance, its really appreciated:

         			<html>
			<head>
			</head>

			<body>
			<script type="text/javascript">
			 function ajaxRequest(){
			 var activexmodes=["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"] //activeX versions to check for in IE
			 if (window.ActiveXObject){ //Test for support for ActiveXObject in IE first (as XMLHttpRequest in IE7 is broken)
			  for (var i=0; i<activexmodes.length; i++){
			   try{
				return new ActiveXObject(activexmodes[i])
			   }
			   catch(e){
				//suppress error
			   }
			  }
			 }
			 else if (window.XMLHttpRequest) // if Mozilla, Safari etc
			  return new XMLHttpRequest()
			 else
			  return false
			}
			  var mygetrequest=new ajaxRequest()
			mygetrequest.onreadystatechange=function(){
			 if (mygetrequest.readyState==4){
			  if (mygetrequest.status==200 || window.location.href.indexOf("http")==-1){
			   document.getElementById("result").innerHTML=mygetrequest.responseText
			  }
			  else{
			   alert("An error has occured making the request")
			  }
			 }
			}
			var namevalue=encodeURIComponent(document.getElementById("name").value)
			var agevalue=encodeURIComponent(document.getElementById("age").value)
			mygetrequest.open("GET", "second.php?name="+namevalue+"&age="+agevalue, true)
			mygetrequest.send(null)

			</script>
				
				
				
				
				
			<form method="get" action="">
			Your name: <input type="text" id="name" name="name" size="25" /> <br />
			Your age: <input type="text" id="age" name="age" size="25" /> <br />
