My Minigame setup. Can you please help me?

I'm having a problem with my minigame setup. There's a GUI in the StarterGui section that is invisible and when the game launches the gui's map text will say Choosing Map. Choosing Map.. Choosing Map... twice but when It get's to the Map chosing part this comes up.
