I'm trying to make a custom camera that is somewhat like shiftlock but in the middle. The position of the camera is correct but it doesn't rotate when moving the mouse. Is there anything I'm doing wrong?

local Players = game:GetService('Players')
local UserInputService = game:GetService('UserInputService')
local ContextActionService = game:GetService('ContextActionService')
local RunService = game:GetService('RunService')

local Camera = workspace.CurrentCamera
local Focus = Vector3.new (0,2,2)
local Zoom = 0

local Player = Players.LocalPlayer

Player.CharacterAdded:connect(function(Character)
	
	Camera.CameraSubject = Character:WaitForChild('Humanoid', math.huge)
	Character.Humanoid.AutoRotate = false
	
	local CamAngleY = 0
	
	local function MouseMove(ActionName, InputState, InputObject)	
		if InputState == Enum.UserInputState.Change then
			
			CamAngleY = math.clamp(CamAngleY - InputObject.Delta.Y*10, -75, 75)
			
			Character.HumanoidRootPart.CFrame = Character.HumanoidRootPart.CFrame * CFrame.Angles(0,math.rad(-InputObject.Delta.X*10),0)
			
		end
	end
	
	ContextActionService:BindAction("MouseMove",MouseMove,false,Enum.UserInputType.MouseMovement)
	
	RunService.RenderStepped:connect(function()
		
		if Camera.CameraType ~= Enum.CameraType.Scriptable then
			Camera.CameraType = Enum.CameraType.Scriptable
		end
		
		local FocusPosition
		
		FocusPosition = Character.HumanoidRootPart.CFrame * CFrame.new(Focus) * CFrame.Angles(math.rad(CamAngleY),0,0)
		Camera.CFrame = FocusPosition * CFrame.new(Vector3.new(0,0,4-Zoom))
		
	end)
end)

function MouseLock(ActionName, InputState, InputObject)
	
	if InputState == Enum.UserInputState.Begin then
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
		ContextActionService:UnbindAction(ActionName)
	end
end

ContextActionService:BindAction("MouseLock",MouseLock,false,Enum.UserInputType.MouseButton1)
