TPS Multiplayer problem

Hello,
I just started using UE4. I watched tutorial on how to make TPS in Unreal Engine 4. Unfortunately I ended on 3td part because something is not working. I used aiming animation and it’s working but the problem is when i launch multiplayer from editor. I chose 2 players and 1 of them is FPS. I don’t know what to do. I hope you can help me.
