JQuery/Json Issue ... Please Help?

Currently we have a page that returns a partners information that can be found at:
http://www.muzak.com/assets/ZipCodeLookup/index.php?zipcode=28037&callback=?
(above is an example with the zipcode already added)

and we are trying to pull the information and save them in hidden form fields using the following code:

var zpcode = document.getElementById('PostalCode').value;
jQuery.getJSON("http://www.muzak.com/assets/ZipCodeLookup/index.php?zipcode=" + zpcode + "&callback=?", 
function(data) {
		
	$("#DealerIA_OA").val('');
	$("MuzakDealer").val('');
	
	$("#DealerIA_OA").val(data["ia_or_oa"]);
	$("#MuzakDealer").val(data["name"]);

});

});

Code (markup):

Any help would be greatly appreciated. Thank you in advance.

 

Be sure you are getting the callback on your index.php page.

Example:
print $_GET['callback']. '('.json_encode($data).')';

 

Thanks I was missing "$_GET['callback']." everything works fine now. Nice find

 

Also, remember, you can write your json by yourself.
