Hi,

You don't need a AJAX packages at all.
I would even suggest you get the thing up and running before diving into
AJAX libs.

A good place to start is www.w3schools.com.
Use their simple browser-independent version to get the xmlhttp object,
and use that for testing.

function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}

And make a simple PHP page, like this:
<?php
echo ((int)$_GET["number"])*2;
?>

Call it from browser:
http://www.example.com/test.php?number=4

It should answer 8.

If that works, try implementing the AJAX logic, like described at
www.w3schools.com.

Remember AJAX is nothing more then a way of getting data from a server
into your webpage via javascript. No reload of the page needed.
