I can get the three cols working but I cannot get the results to go to my script. I've tried dozens of different ways of the following code. Sorry for being such a noob!

1.   $(function() {
       $("#sortable1, #sortable2, #sortable3").sortable({
         connectWith: '.connectedSortable',
         update : function () {
             var sort1 = $("#sortable1").sortable('serialize');
               $("#AjaxResult").load("update.php?col=1"+sort1);
             var sort2 = $("#sortable2").sortable('serialize');
               $("#AjaxResult").load("update.php?col=2"+sort2);
             var sort3 = $("#sortable3").sortable('serialize');
               $("#AjaxResult").load("update.php?col=3"+sort3);
         }
       });
   });
