CAN SOME ONE HELP ME WITH DATA SAVING AND LOADING?

Hi, Can some one please help me? i try to save and load my data in the playerdatastore. but i dont know what is wrong with it, and as i see nothing is wrong at all. i dont get errors but also my data wont save and or load. i looked up a tutorial and did every thing they say in it, put api on on site and every thing, but still not working.

Please help!

so i have this code:

local currencyNameA = "Coins"
local currencyNameB = "Gold"

local DataStore = game:GetService("DataStoreService"):GetDataStore("PlrDataStore")

game.Players.PlayerAdded:Connect(function(player)

	local folder = Instance.new("Folder")
	folder.Name = "leaderstats"
	folder.Parent = player

	local currencyA = Instance.new("IntValue")
	currencyA.Name = currencyNameA
	currencyA.Parent = folder

	local currencyB = Instance.new("IntValue")
	currencyB.Name = currencyNameB
	currencyB.Parent = folder
	
	local aID = currencyNameA.."_"..player.UserId
	local bID = currencyNameB.."_"..player.UserId
	local asavedData = nil
	local bsavedData = nil

	pcall(function()
		asavedData = DataStore:GetAsync(aID)
		bsavedData = DataStore:GetAsync(bID)
	end)

	if asavedData ~= nil and bsavedData ~= nil then
		currencyA.Value = asavedData
		currencyB.Value = bsavedData
		print("Data loaded")
	else
		-- New Player
		currencyA.Value = 0
		currencyB.Value = 0
		print("New Player to the game")
	end

end)

game.Players.PlayerRemoving:Connect(function(player)

	local aID = currencyNameA.."_"..player.UserId
	local bID = currencyNameB.."_"..player.UserId
	DataStore:SetAsync(aID,player.leaderstats[currencyNameA].Value)
	DataStore:SetAsync(bID,player.leaderstats[currencyNameB].Value)
	print("Data saved")
end)

game:BindToClose(function()

	-- When game is ready to shutdown

	for i, player in pairs(game.Players:GetPlayers()) do
		if player then
			player:Kick("This game is shutting down or restarting!")
		end
	end

	wait(5)

end)
