Unable to look up or down for unknown reasons

i was fixing some bugs the other day regarding crouching. but now my character is unable to look up or down. its a first person controller and since first making it, i have not touched the mouse control code once. im guessing it has something to do with the inspector because i did mess with that a bit, but i do not know for sure.
heres the inspector for reference

and heres the code

Is “Use Pawn Control Rotation” checked in your Camera component?

no it was not, this worked great
