Drag and drop with multiple movie clip

Hi There;

Referring to the tutorial at http://www.hed.swin.edu.au/design/tutorials/flash/drag_drop_tut/index.php#five (under the title of drag multiple object), i would like to make it allow the circle_mc able to drop into the targetCircle and targetCircle2 as well. Same to circle_mc2. That would mean, i am free from dragging the circle_mc to any target without the restrition. As the tutorial given only allow me to draging circle_mc to targetCircle and circle_mc2 to targetCircle2.

I taught of adding addtional 2 action script for;
dragSetup(circle_mc,targetCircle2);
dragSetup(circle2_mc,targetCircle);

but no luck…

Please help… as I m new to Flash but need to work on something that similar like this.

Thank you.
