javascript not working in ie7

This code works in firefox but not in ie7.  It also makes all of my other javascript codes fail in ie7.  Does anybody see something wrong with it.

$("#account_info").validate( {
							
	  errorPlacement: function (error, element) {  //puts the error message beside the label    
	   $('#'+element.attr("id")+'_label').append(error); 		 
         },
		 
		 
	  rules: { 
       profile_2: { profileNotEqualTo: "#profile_1"}, //profile 1 cannot be equal to profile 2  
	     },
		 
	  messages: { // custom messages
	   county_ansi: "Setting your location is required. Please enter a city or zip code to search."
		 },
		 
	  submitHandler: function(form) { //submits form and hide button shows loading
       $("#loading_box").show();
       $("#button_box").hide();
	   form.submit();    
         }
		 
	     });
