Swapping movie clips

1

i have two buttons, each calls up a different movie clip to the stage. when you click each button again, the movieclip closes. i’m trying to figure out how to make it so that if one button’s movie clip is open and you click another button, the second buttons movieclip will swap places with the first. (for instance if you click button 1 then button 2 without closing the button 1 movie clip, they overlap) i’m including the file too. the buttons im talking about are the 2nd and third from the left. thanks!
