Cinematic camera used as first person camera - help!

Hey! so i want to use the cinematic camera for the first person view camera for obvious reasons. but when i do switch out cameras, i get the compile errors telling me to add “self” (cinematic camera) so i do so, and then i hit play, it works, BUT, i cannot look up or down, it is only left and right, please help! would love to set this up for an incredible FPS Horror game i am making! =)
