[SOLVED] Developer Product process receipt failure?

The script is to give the player an amount of cash when they buy it. When tested only one script (ount of four) work.

Working script:

local MPS = game:GetService("MarketplaceService")

MPS.ProcessReceipt = function(receiptInfo)
	if receiptInfo.ProductId == 1087304694 then
		local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
		player.leaderstat.Cash.Value = player.leaderstat.Cash.Value + 1000
		return Enum.ProductPurchaseDecision.PurchaseGranted
		
	elseif receiptInfo.ProductId == 0 then
		local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
		print("Cannot buy")
		return Enum.ProductPurchaseDecision.PurchaseGranted
	end
end

Failing script:

local MPS = game:GetService("MarketplaceService")

MPS.ProcessReceipt = function(receiptInfo)
	if receiptInfo.ProductId == 1087304716 then
		local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
		player.leaderstat.Strength.Value = player.leaderstat.Strength.Value + 1000
		return Enum.ProductPurchaseDecision.PurchaseGranted
		
	elseif receiptInfo.ProductId == 0 then
		local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
		print("Cannot buy")
		return Enum.ProductPurchaseDecision.PurchaseGranted
	end
end
