Rails spinoffs - Sep 2007 - Create an AJAX function with prototype. Cant return data

Hey all I am trying to create a Prototype Ajax functino that will
return the data out of the fuinction.  Here is my code
[code]
function SendData(urlString,url)
{
				var opt = {
				    // Use POST
				    method: ''post'',
				    // Send this lovely data
				    //postBody: ''p1=firsttime'',
					postBody: urlString,
				    // Handle successful response
				    onSuccess: function(t) {
						// Sending the responcd to be parsed and entered in the correct
places
				        alert("From withing the function ** " + t.responseText +
"
**");
						return(t.responseText); // <---- Trying to return data
				    },
				    // Handle 404
				    on404: function(t) {
				        alert(''Error 404: location "'' + t.statusText
+ ''" was not
found.'');
				    },
				    // Handle other errors
				    onFailure: function(t) {
				        alert(''Error '' + t.status + '' --
'' + t.statusText);
				    }
				}
				return returnData;  // <-------Trying to return data
				new Ajax.Request(url, opt);

}
		</script>
		<script type="text/javascript">
			function doME()
			{
				var test =
SendData(''lala'',''http://miys02ae211935l/learn/
dhtmlwindow/showme.php'');
                                 alert(test);
			}
[/code]

in the doMe function I would like to return the var test from the
SendData Function.  Not sure why this is not working.

Thanks,
timgerr
