hey everyone im having some trouble with the drag & drop. i have drag working perfect until i add droppable.

<script type="text/javascript">
$j(".drag").draggable({helper: 'clone'});
accept: ".drag",
activeClass: 'droppable-active',
hoverClass: 'droppable-hover',
drop: function(ev, ui) {

the error that I am receiving is Error: m is undefined in ui.droppable.js

which is this line:

droppablesLoop: for (var i = 0; i < m.length; i++) {

anyone have any clue?
