Why is the checkpoint teleport script is not working? Please help me!

I am a bit confused about my script. Because the detecting part works perfectly and the teleport command is also logical, but I when I test it then it will detect if the player died but will not teleport the player to that location.

Here is my script (print(“Success!”) is because for testing if the detecting part works):

game.Players.PlayerAdded:Connect(function(player)
	print(player)
	local spawn = false
	script.Parent.Touched:Connect(function(hit)
		print("Success!")
		if hit.Parent:FindFirstChild("Humanoid") and hit.Parent.Name == player.Name then
			spawn = true
		end
	end)
	player.CharacterAdded:Connect(function(character)
		print("Success!")
		if spawn == true then
			print("Success!")
			character.HumanoidRootPart.CFrame = CFrame.new(script.Parent.Position.X,script.Parent.Position.Y+5,script.Parent.Position.Z)
		end
	end)
end)

My script is a script, not a local or module script. If you know why it is not working, then please point it out for me. I do not need how to make a checkpoint, I just need why is this not working. If you know then please tell me, thanks.

I have a checkpoint for my script and it's working so use that:

local Players = game:GetService("Players")
local spawn = script.Parent

script.Parent.Touched:Connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if hit.Parent and hit.Parent:FindFirstChild("Humanoid") then
		local checkpointData = game.ServerStorage:FindFirstChild("CheckpointData")
		if not checkpointData then
			checkpointData = Instance.new("Model", game.ServerStorage)
			checkpointData.Name = "CheckpointData"
		end
		local checkpoint = checkpointData:FindFirstChild(tostring(player.userId))
		if not checkpoint then
			checkpoint = Instance.new("ObjectValue", checkpointData)
			checkpoint.Name = tostring(player.userId)

			player.CharacterAdded:connect(function(character)
				wait()
				character:WaitForChild("UpperTorso").CFrame = game.ServerStorage.CheckpointData[tostring(player.userId)].Value.CFrame + Vector3.new(0, 4, 0)
			end)
		end
		checkpoint.Value = spawn
	end
end)
