My script's end on line 24 isn't working, it says it is a fail but I'm not sure what to do?

Im not sure why it isn't working but all I know that it isn't. Im trying to learn Lua so I'd really like some help!

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Parent = leaderstats
	
	local data
	local sucess, errormessage = pcall (function()
		data = myDataStore:GetAsync(player.UsedId.."-cash")
	end)
	
	if sucess then
		cash.Value = data
	else
		print("There was an error whilst getting your data")
		game.StarterGui.ScreenGui.TextLabel.Visible = not "TextLabel" Visible
		end) -- WHERE IT IS FAILING!

game.Players.PlayerRemoving:Connect(function(player)
	
	local sucess, errormessage = pcall (function()
		myDataStore:SetAsync(player.UserId.."-cash",player.leaderstats.Cash.value)
end)

	if sucess then
		print("Player Data Sucessfully Saved!")
	else
		print ("there was an when saving data!")
		warn(errormessage)
	end

end)
