Why this devproduct script don't add gold to player?

Hello, I have problem with devproducts. When player buy gold it won't add him it.

Here is script:

game.StarterGui.ResetPlayerGuiOnSpawn = false

local MarketplaceService = game:GetService("MarketplaceService")

function getPlayerFromId(id)
	for i,v in pairs(game.Players:GetChildren()) do
		if v.userId == id then
			return v
		end
	end
	return nil
end
 
MarketplaceService.ProcessReceipt = function(receiptInfo)
	local productId = receiptInfo.ProductId
	local playerId = receiptInfo.PlayerId
	local player = getPlayerFromId(playerId)
	local productName 
	if productId == 32364216 then
		productName = "2,000G"
		local cashmoney = game.leaderstats.Gold:FindFirstChild(player.Name)
		if cashmoney then
			cashmoney.Value = cashmoney.Value + 2000
		end
	elseif productId == 32364229 then
		productName = "5,000G"
		local cashmoney = game.leaderstats.Gold:FindFirstChild(player.Name)
		if cashmoney then
			cashmoney.Value = cashmoney.Value + 5000
		end
	elseif productId == 32364246 then
		productName = "10,000G"
		local cashmoney = game.leaderstats.Gold:FindFirstChild(player.Name)
		if cashmoney then
			cashmoney.Value = cashmoney.Value + 10000
		end
		end
	local message = Instance.new("Hint",workspace)
	message.Text = player.Name.." purchased "..productName.."!"
	coroutine.resume(coroutine.create(function()
		wait(2)
		message:destroy()
	end))

	return Enum.ProductPurchaseDecision.PurchaseGranted		
end

I think local cashmoney is wrote wrong...
