How to sell multi dev products?

I made a gui shop for buy cash in game [TYCOON] I made 2 test "Buy 500 Cash" and " Buy 1000 Cash" The 1000 works the 500 not

This script going in my TextButtom from my gui; [1000 Cash]

local productId = 22197517 
local player = game.Players.LocalPlayer

script.Parent.MouseButton1Click:connect(function()
	Game:GetService("MarketplaceService"):PromptProductPurchase(player, productId)
end)

This script in starterpack;

local MarketplaceService = Game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
 
CASHID = 22197517 -- Put the Developer Product ID here

MarketplaceService.ProcessReceipt = function(receiptInfo)
	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_product_" .. receiptInfo.ProductId
	local numberBought = ds:IncrementAsync(playerProductKey, 11)
	for i,v in pairs (game.Players:GetChildren()) do
		if v.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == CASHID then
			
			
				lds = v:FindFirstChild("leaderstats")
				if lds ~= nil then
					cs = lds:FindFirstChild("Cash") --Change to your leaderstat
					if cs ~= nil then
						cs.Value = cs.Value + 1000 --Change to the amount you want this to add
					end
				end
			end
		end
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted		
end

This works but when in do the 500 cash [First script the same] Starterpack

local MarketplaceService = Game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
 
CASHID = 22197521 -- Put the Developer Product ID here

MarketplaceService.ProcessReceipt = function(receiptInfo)
	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_product_" .. receiptInfo.ProductId
	local numberBought = ds:IncrementAsync(playerProductKey, 1)
	for i,v in pairs (game.Players:GetChildren()) do
		if v.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == CASHID then
			
			
				lds = v:FindFirstChild("leaderstats")
				if lds ~= nil then
					cs = lds:FindFirstChild("Cash") --Change to your leaderstat
					if cs ~= nil then
						cs.Value = cs.Value + 500 --Change to the amount you want this to add
					end
				end
			end
		end
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted		
end

This does not work... And i already did change

local numberBought = ds:IncrementAsync(playerProductKey, 1) --To 11 or 14 (14 is number where product is)

I hope some one can help me Thanks you :)
