Skip Stage script works with one button, but not another?

I have an obby, and there is a skip stage button. There is a skip 10 stages, and skip 1. The skip 1 works fine, but skip 10 is broken. Here is the local script in it:

local productId = 53038472
local player = game.Players.LocalPlayer
script.Parent.MouseButton1Click:connect(function()
	game:GetService("MarketplaceService"):PromptProductPurchase(player, productId)
end)

Here is the other script that isnt local:

MarketplaceService = game:GetService("MarketplaceService")

MarketplaceService.ProcessReceipt = function(receiptInfo)
players = game.Players:GetPlayers()

currency = "Stage"

done = 0

for i=1,#players do
	if players[i].userId == receiptInfo.PlayerId then
		if receiptInfo.ProductId == 53038472 and done == 0 then
			done = 1
			players[i].leaderstats[currency].Value = players[i].leaderstats[currency].Value + 10
			players[i].Character.Humanoid.Health = 0
			done = 0
		end
	end
end
return Enum.ProductPurchaseDecision.PurchaseGranted	
end

these seem so perfect, whats wrong?

Check your output and see what ends up printing.

local MarketplaceService = game:GetService("MarketplaceService")
local currency = "Stage"
MarketplaceService.ProcessReceipt = function(receiptInfo)
	local player = game:GetService("Players"):GetPlayerByUserId(receiptInfo.PlayerId)
	if not player then
		return Enum.ProductPurchaseDecision.NotProcessedYet 
	end
	if receiptInfo.ProductId == 53038472 then 
		print("Correct receipt")
		local leaderstats = player:findFirstChild("leaderstats")
		if leaderstats then 
			print("Found leaderstats")
			local currency = leaderstats:findFirstChild(currency)
			if currency then 
				print("Found currency")
				currency.Value = currency.Value + 10
				player:LoadCharacter()
			end
	    end
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted 
end
