this, and all of my other checkpoint scripts wont work. how do i fix it?

im trying to make a checkpoint but every single script i use isn't working. this is the code i came up with:

local spawn = script.Parent
spawn.Touched:connect(function(hit)
if hit and hit.Parent and hit.Parent:FindFirstChild("Humanoid") then
local player = game.Players:GetPlayerFromCharacter(hit.Parent)
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("HumanoidRootPart").CFrame = game.ServerStorage.CheckpointData[tostring(player.userId)].Value.CFrame + Vector3.new(0, 4, 0)
end)
end checkpoint.Value = spawn
end
end

if you notice that i made a mistake in the code, or if this is outdated, please let me know. thanks from poopypigeon245
