flash skeleton drag-drop "game" changes

I have a ready-made drag-drop interactive film made with Flash; it's totally done but just needs a few changes which I simply don't have time to do myself. Right now, you drag all the bones onto the area from the left hand-side to the right hand-side. Dump them into the right place, the skeleton is formed and moves as a little reward. The change is that the bones which are right AND left (marked in the word document) have to be LINKED - meaning, they have to drag together and appear in the final skeleton together as if they were one bone, so the drag object for those items will consist of two bones rather than one. The word document shows which bones are the linked ones (a-a, b-b, c-c etc.) Have a look at the FLA, export the SWF and see how it all works. This item needs to be built and tested by wednesday pm Amsterdam time. PLease don't hesitate to ask any questions if anything is unclear. it's probably about 2 hours of work inc. testing. I will need the FLA back when it's done, and not just the SWF.
