why won't my camera move (localscript)?

I need my camera to move up and down during the animation (trying to get a shake effect)? Warning long!

LocalScript:

--Starting Varibles
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local camera = game.Workspace.CurrentCamera


--Keypressed
mouse.KeyDown:connect(function(key)
	--Find keybind
	local keybind = script.Parent.KeybindText.Text
	--Check keybind
    if key:lower() == keybind or key:upper() == keybind then
		--Camera
		script.Parent.Parent.Parent.OnOff.Visible = false
        game.Workspace[player.Name].Humanoid.WalkSpeed = 0
		local newCamera = Instance.new("Part", game.Workspace[player.Name].Head)
		newCamera.Name = "localNewCamera"
		newCamera.Anchored = true
		newCamera.CanCollide = false
		local oy = game.Workspace[player.Name].Head.Orientation.Y
		local ox = game.Workspace[player.Name].Head.Orientation.Y
		wait(0.01)
		newCamera.Orientation = Vector3.new(0,oy -180,0)
		newCamera.Transparency = 1
		wait(0.01)
		local x = game.Workspace[player.Name].Head.Position.X
		local y = game.Workspace[player.Name].Head.Position.Y
		local z = game.Workspace[player.Name].Head.Position.Z
		wait(0.01)
		newCamera.Position = Vector3.new(x,y -1,z - 5)
		wait(0.01)
		camera.CameraType = "Scriptable"
		camera.CFrame = game.Workspace[player.Name].Head.localNewCamera.CFrame
		--Animation
		local animation = Instance.new("Animation")
		animation.AnimationId = "rbxassetid://2544696183"
		local humanoid = game.Workspace[player.Name]:WaitForChild("Humanoid")
		wait(0.01)
		local track = humanoid:LoadAnimation(animation)
		wait(0.2)
		track:Play()
		for i = 1,20 do
			wait(0.1)
			local nx = newCamera.Position.X
			local ny = newCamera.Position.Y
			local nz = newCamera.Position.Z
			wait(0.1)
			newCamera.CFrame = CFrame.new(nx,ny +0.1,nz)
			wait(0.1)
			newCamera.CFrame = CFrame.new(nx,ny -0.1,nz)
		end
    end
end)
