You seem to be incorrectly tagged as php. Also have you considered jQuery for the ease of ajax whilst using it.

as for your question could you post the code on the page where the ajax request is going to as the code here looks fine..

Edit: Where is serverScript set? change serverScript for the ajax page you are calling? http://msdn.microsoft.com/en-us/library/windows/desktop/ms757849%28v=vs.85%29.aspx
