First-Person Character Won't Move Or Jump

I’m trying to make a first person shooter. My problem is that the player only moves left or right. It won’t move forward or backwards or jump. Does anyone know how to fix this?

You can use 3D shooter keyboard mapper behavior and that’s it.
but still your code is actually right and should’ve worked.
Maybe you don’t have the ground with 3D physics engine or Your walkspeed is not right.
I still recommend using the 3D shooter keyboard mapper because it just makes things easier, only if you want to make custom movement or something like that i recommend sticking with what your doing.
