can somone please help me fix a script for my game? thank you

so my scripts are suppose to disable the controls which it does then switch the camera and only allow D and D to be pressed

the parts or scripts i have in my workspace:

CameraLineEnd <part CameraLinePos<part CameraLineStart<part LocalPlayerCameraPart<Part

that is suppose to allow the player camera to not go past the end and start pos

scripts:

playerenters main CameraControls CameraManipulation

CameraControls :

repeat

wait (.1)
until game.Workspace.LocalPlayerCameraPart
local camobj = game.Workspace.LocalPlayerCameraPart

function onKeyPress(inputObject, gameProcessedEvent)
    if inputObject.KeyCode == Enum.KeyCode.D then
    print("D was presssed")
    camobj.MovmentValue.Value = "Right"
    elseif inputObject.Keycode == Enum.Keycode.A then
    print ("A was pressed")
    camobj.Movementvalue.Value = "Left"
    end 
end
function onKeyLet (inputObject, gameProcessedEvent)
    if inputObject.KeyCode == Enum.Keycode.D then 
        print ("D was let")
        camobj.MovementValue.Value = "none"
    elseif inputObject.keycode == Enum.KeyCode.A then
        print ("A was let")
        camobj.MoveMentValue.Value = "none"
    end

end
game:GetService("UserInputService").InputBegan:connect(onKeyPress)
game:GetService("UserInputService").InputEnded:connect(onKeyLet)

CameraManipulation :

 local camera = game.Workspace.CurrentCamera

        end

        camera.CameraSubject = part
        camera.CoordinateFrame = part2.CFrame
        camera.FieldOfView = 50

even though if nobody can help me with this i would love to thank everyone for atleast trying and looking at my thread :)
