Data saves but doesn't give to player

Help and Feedback Scripting Support
#1

How can I edit this script to retrieve the data from datastore and give it to the player? Are there any errors in my code? I’m new to coding so I’m using tutorials to help me learn code.

local DataStoreService = game:GetService("DataStoreService")
local CashDataStore = DataStoreService:GetDataStore("CashDataStore")

function onPlayerEntered(newPlayer)
	local success, cashValue = pcall(function()
		return CashDataStore:GetAsync(newPlayer.UserId)
	end)
	if not success then
		-- an error occurred while trying to retrieve the value from the DataStore
		-- you can log the error message or take some other action here
		print("Error retrieving cash value from DataStore: " .. cashValue)
		return
	end

	local stat = newPlayer:FindFirstChild("leaderstats")
	if not stat then
		stat = Instance.new("IntValue")
		stat.Name = "leaderstats"
		stat.Parent = newPlayer
	end

	local cash = stat:FindFirstChild("Cash")
	if not cash then
		cash = Instance.new("IntValue")
		cash.Name = "Cash"
		cash.Parent = stat
	end

	cash.Value = cashValue
end

game.Players.ChildAdded:Connect(onPlayerEntered)

Any help would be greatly appreciated and if possible I would like for you to explain why certain things work. Thank you!!

local DataStoreService = game:GetService("DataStoreService")
local CashDataStore = DataStoreService:GetDataStore("CashDataStore")

game.Players.PlayerAdded:Connect(function(Plr)
   -- Stats
   local ls = Instance.new("Folder", Plr)
   ls.Name = "leaderstats"
   local cs = Instance.new("IntValue", ls)
   cs.Name = "cash"
   --
   local Success, Data = pcall(function()
      return CashDataStore:GetAsync(Plr.UserId) -- returns Data
   end)
   if Success then -- If Accessed DataStores
      if Data then -- If Data found
         cs.Value = Data -- Value is equal to Data
      else -- If No Data
         cs.Value = 0 -- No Data
      end
   else -- If Failed to Access DataStores
      Plr:Kick("Error in loading data!") -- Kicks Player
   end

end)

Here, try this!

local CashDataStore = DataStoreService:GetDataStore("CashDataStore")

function onPlayerEntered(newPlayer)
local CashData
	local success, fail = pcall(function()
		CashData CashDataStore:GetAsync(newPlayer.UserId)
	end)
	if not success then
		-- an error occurred while trying to retrieve the value from the DataStore
		-- you can log the error message or take some other action here
		print("Error retrieving cash value from DataStore: " .. cashValue)
		return
	end

	local stat = newPlayer:FindFirstChild("leaderstats")
	if not stat then
		stat = Instance.new("IntValue")
		stat.Name = "leaderstats"
		stat.Parent = newPlayer
	end

	local cash = stat:FindFirstChild("Cash")
	if not cash then
		cash = Instance.new("IntValue")
		cash.Name = "Cash"
		cash.Parent = stat
	end

	cash.Value = CashData
end

game.Players.ChildAdded:Connect(onPlayerEntered)
