$.ajax and JSON Response

$.ajax and JSON Response

Hi,

I'm having a tough time getting at the values I want in this ajax response.

Here is the response

{"COLUMNS":["SITE_ID","PARENT_ID","DISPLAY_NAME"],"DATA":[[87,19,"The Site Name"],[2,19,"Another Site Name"]]}

success: function(resp){
      alert(   resp.DATA.length ); // this works, shows me the right number
     var options = '';
     for (var i = 0; i < resp.DATA.length; i++) {
      options += '<option value="' + resp.DATA[i].SITE_ID + '">' + resp.DATA[i].DISPLAY_NAME + '</option>';
     }
}

I'm trying to get the value of the "site_id" and the "display_name" column but I can't get it right.

Anyone see anything wrong??

Thanks,
