Why is domination the only working game mode out of 3?

Alright, What the script is supposed to do is -Choose a game mode (3 game modes, domination,freeforall, and team deathmatch) -Choose a random map -Make the teams then start then start it But for some reason domination is the only one working, The others are stuck on making teams part.. Here is the script and thanks for taking you time to help!
