Scaling and moving movieclips

hi all.
need urgent help with something.
i have 3 movieclips lined up horizontally on the stage. i want to do a few things;

  • on each button rollover/rollout, the button scales up/down around 200% and ‘pushes/pulls’ the other buttons either side so that the distance between each one is maintained and there’s not overlap.
  • onclick, the button scales up about 400% and moves below the others. the gap is leaves gets ‘filled’ by the other buttons moving into its place.

i found a site that does pretty much exactly what i’m after - www.hansthedouble.com.

help would be appreciated.

thanks
