Thank you,

try this:

var selected_div = $("input#selected_div").val();
var isDraggable;
if(selected_div == "68") isDraggable = true;
else isDraggable = false

$("#a68").draggable({ 
          containment: 'parent',
          disabled: isDraggable,
          handle: 'drag_border',
          drag: function(e, ui) {
                 var top = ui.position.top;
                 var left = ui.position.left;
                 $("input#tuPBd0hm_top").val(top);
                 $("input#tuPBd0hm_left").val(left);
                 $("#top").html(top);
                 $("#left").html(left);
          }
});

And if you want to be able to disable or enable the div from being draggable after the page has been loaded then look at jquery Draggable API and click the Methods tab

$("#a68").draggable("disable");
$("#a68").draggable("enable");

I hope this helps!

An ID in html must begin with a letter, so "#68" really shouldn't select anything. Try putting a letterr a-z in the front of the ID.
