How to check if a product is purchased or no ?

game:GetService("MarketplaceService").PromptPurchaseFinished:connect(function(Player,ID,purchased)
	if Purchased then
		print(Player.Name .. " bought an item with AssetID: " .. ID)
	else
		print(Player.Name .. " didn't buy an item with AssetID: " .. ID)
	end
end)

But it doesn't print "X bought an item with AssetID: 12345".
