Train door will not open?

I installed train doors into my metro train and it's basically a left union and inside is the parts used for the position ( like OpenPos and ClosePos )

Now I wanted 1 side to open for my game so I added an if statement so like If side ( Variable ) Is "Right" Then do the tween but now it doesn't work? I added some prints and everything was fine so please help.

door script

local this = script.Parent

local TweenService = game:GetService("TweenService")

local TrainDoor = this.Carriage.TrainDoor
local Event = this.OpenDoors

local doortweenInfo = TweenInfo.new(1, Enum.EasingStyle.Cubic, Enum.EasingDirection.InOut, 0, false, 0)

function Anchor(model)
	for i, v in pairs(model:GetChildren()) do
		if v:IsA("UnionOperation") then
			v.Anchored = true
		end
	end
end
function UnAnchor(model)
	for i, v in pairs(model:GetChildren()) do
		if v:IsA("UnionOperation") then
			v.Anchored = false
		end
	end
end
Event.Event:Connect(function(side)
	print(side)
	if side == "Right" then
		print("Is right")
		for i,v in pairs(TrainDoor.RightSide:GetChildren()) do
			if v.Name == "DoorL" then
				print("Is doorL")
				Anchor(TrainDoor)
				
				TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosOpen.Position)}):Play()
				delay(5, function()
					TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosClosed.Position)}):Play()
					wait(1)
					UnAnchor(TrainDoor)
				end)
			end
			if v.Name == "DoorR" then
				print("Is doorR")
				Anchor(TrainDoor)
				TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosOpen.Position)}):Play()
				delay(5, function()
					TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosClosed.Position)}):Play()
					wait(1)
					UnAnchor(TrainDoor)
				end)
			end
		end
	elseif side == "Left" then
		print("Is left")
		for i,v in pairs(TrainDoor.LeftSide:GetChildren()) do
			if v.Name == "DoorL" then
				Anchor(TrainDoor)

				TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosOpen.Position)}):Play()
				delay(5, function()
					TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosClosed.Position)}):Play()
					wait(1)
					UnAnchor(TrainDoor)
				end)
			end
			if v.Name == "DoorR" then
				Anchor(TrainDoor)
				Anchor(TrainDoor)
				TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosOpen.Position)}):Play()
				delay(5, function()
					TweenService:Create(v, doortweenInfo, {CFrame = CFrame.new(v.PosClosed.Position)}):Play()
					wait(1)
					UnAnchor(TrainDoor)
				end)
			end
		end
	end
