AJAX shoutbox help

would anyone be kind enough to help me with my AJAX shoutbox which isn't working.

It posts to the shoutbox but it doesn't display the shouts.

function showData() {
	htmlRequest = ajaxFunction();
	if (htmlRequest==null){ // If it cannot create a new Xmlhttp object.
		alert ("Browser does not support HTTP Request");
		return;
	} 

	htmlRequest.onreadystatechange = function(){
		if(htmlRequest.readyState == 4){
			document.getElementById("shoutarea").innerHTML = htmlRequest.responseText;
		}
	}
	htmlRequest.open("GET", "http://www.nanoy.org/AjaxShoutbox/outputinfo.php", true);
	htmlRequest.send(null);
}

thats the bit I think is wrong. any help would be nice! (pm me if you wan't the url. or for my MSN addy

cheers in advance

You didn't post the whole code but what i see is it's not closed (didn't give the next line in your shot) The next line should read "showData();" To finish the display.
