Developer Product Gui shop problem?

I have a Gui shop for purchasing developer products which award "cash" on the Leaderboard. Now this script works, however it only works for one of the developer products. The one that awards 500 cash. When you pay for the other Developer products nothing happens within the leaderboard. I use the same code below for all the products, just changing the ID, and cash award values. However only the 500 cash button works. I have no idea why.

local MarketplaceService = Game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory") 

CASHID = 19990870

 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") 
					if cs ~= nil then
						cs.Value = cs.Value + 500 
					end
				end
			end
		end
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted
end
