My developer product handler is giving me a wearde error?

Wearde... So at first, I got an error I believe I fixed it. Please help me fix this script:
Also the error its giveing me is: ServerScriptService.BuyCash.1:26: unexpected symbol near '?'

-- setup local variables
local MarketplaceService = Game:GetService("MarketplaceService")
local productId = 236341078



-- define function that will be called when purchase finished
MarketplaceService.ProcessReceipt = function(receiptInfo) 

 -- find the player based on the PlayerId in receiptInfo
 for i, player in ipairs(game.Players:GetChildren()) do
  if player.userId == receiptInfo.PlayerId then


   -- check which product was purchased
   if receiptInfo.ProductId == productId then


   -- give them the cash
   player.leaderstats.Money.Value = player.leaderstats.Money.Value + 250   
   end
  end
 end 
 -- tell ROBLOX that we have successfully handled the transaction
 return Enum.ProductPurchaseDecision.PurchaseGranted  
end)

Also if you're going to fix it do not give me a link to the Roblox wiki or something please give me the script or tell me why this is happening and help me fix it..
