Re-Creating MSN Spaces click'n'drag tables

Hello all!

Completely out of interest, I have taken the idea of the MSN spaces website (http://spaces.msn.com), and their ASP table methods.

So far, I have made a simple grid of 4 squares and am able to click and drag one draggable movieclip to each cell using the on(press), on(release) methods. But I have a problem when I start introducing more than one dragable movieclip. I want to ultimately have movieclips which when you drag one over another, that is replaced (get it?). Anyway, I need someone who has tried this before (if not, an experiences Actioncripter, Animator) due to my amatuarishness (not even a word).

I can upload files for those willing to help, so just ask :d:
