Shoutbox not reloading

[O1DMBFan]

I've built a shoutbox as my first AJAX project. I have two pages. For simplicity's sake of this post we'll say the shoutbox will only display the two most recent messages.

First Page (serverprint.asp):
Asp page that outputs the following string into the body:
10/17/2009 10:07:18 AM'Chuckycharms'please by the freak of nature work'10/16/2009 11:32:16 PM'Chuckycharms'try it now'

Second Page (default2.asp):
Javascript/AJAX code that displays and updates messages every 1000ms.

<table>	
    <tr>
      <td bgcolor="#666666"><div id="gamer1"><? echo $gamer_1; ?></div>:<div id="message1"><? echo $message_1; ?></div>--<div id="time1"><? echo $time_1; ?></div></td>
    </tr>
    <tr>
      <td bgcolor="#999999"><div id="gamer2"><? echo $gamer_2; ?></div>:<div id="message2"><? echo $message_2; ?></div>--<div id="time2"><? echo $time_2; ?></div></td>
    </tr>
</table>

<script type="text/javascript">
	var getv=-1;
	var page="http://www.xxx.com/shoutbox/serverprint.asp";
	
	function getData(){
		while(getv!=-1){}
			if (window.XMLHttpRequest) {
				getv= new XMLHttpRequest();
			if (getv.overrideMimeType){
				getv.overrideMimeType("text/xml");
			}
			}else if (window.ActiveXObject) {
				try {
					getv = new ActiveXObject("Msxml2.xmlHttp");
					getv.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
				}catch (e) {
				try {
					getv= new ActiveXObject("Microsoft.xmlHttp");
				}catch (e) {}
				}
			}
			ret=-1;
			getv.onreadystatechange = function(){
				if (getv.readyState == 4) {
					ret=getv.responseText;
					update(ret);
					getv=-1;
				}
			};
			getv.open("POST", page);
			try{
				getv.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
			}catch(e){}
				getv.send("");
				return ret;

				return 0;
				setTimeout("getData()",1000);
			}

			function update(value){
				var data=value.split("'");
				document.getElementById("gamer1").innerHTML=data[0];
				document.getElementById("message1").innerHTML=data[1];
				document.getElementById("time1").innerHTML=data[2];
				document.getElementById("gamer2").innerHTML=data[3];
				document.getElementById("message2").innerHTML=data[4];
				document.getElementById("time2").innerHTML=data[5];
			}
			window.onload = getData;
</script>

Page 2 initially loads the information correctly but does not attempt to update it every second. I am a beginner at AJAX so don't over-estimate my abilities and assume I am ignorant.
