[RTS] Need Button Info

Part.2-- the building.
i have a movieclip with 2 frames and a button in side. the button is a pic of a building. on both frames the buttons actions are

on (release) {
gotoAndStop(2);
}
on (releaseOutside) {
gotoAndStop(1);
}

frame1=building unselected
frame2=building selected

is it the (releaseoutside)?
