Unity 2 player 2D game using photon with PUN 2

Need help getting the 2-player lobby and level selection to work. I have made sample scenes with 2 separate player spawners. I have also started setting up the level selection and the host and join functions, but I have not been able to make it work. the room also needs to be restricted to 2 players. There also needs to be something to distinguish player 1 and player 2 to make sure they do not come out of the same spawner.
