basic actionscript button action that can be attached directly to a button on the stage.  this will NOT work in actionscript 3, which does not allow actionscript to be attached directly onto buttons.

make sure you're attaching this action to a button and not to a keyframe on the timeline.  the actions window should say "actions - button" when you open it.  if it says "actions - frame" you're trying to attach this action to the timeline and flash will blow a fuse!
