Funtions and Frame Labels

Ok I have created a function that tweens a box on to the stage and this function is attached to every btn on stage. What i can figure out is how to create a function to get it to go to a frame the movie clip that comes in. I have attached the fla and when you go to the main stage you will see a blk box off stage in that box in where i want when someone clicks the button it goes to a specific frame label. I have no clue how to do this so any help would be great.
