This script working great on FireFox and Chrome
but on IE it loads the pages without sending the parameters

Code JavaScript:
	$(document).ready(function() {
			$(document).ready(function() {
		$("#SearchResult").load("ajax_Search.php", { fname: "", lname:"" });
 
		  $("#changeForm").click(function () {
			$("#SearchForms").load("ajax_searchForms.php", { form: "advanced" });
			return true;
		});
 
		$("#sort_dropdown").live("click", function(event){						
			$("#sort_dropdown").change(function () {
				var values = $("#sort_dropdown").val();
				$("#SearchResult").load("ajax_Search.php", {  fname: "", lname:"", sort: values });
			});
		});
	});
