local function giftHandler()

		if status == true then
			local playerName = game.Players:GetPlayerByUserId(player)
			print(playerName)
			local playerToGift = playerName:FindFirstChild("OtherStats"):FindFirstChild("GiftTo").Value

				local val = Instance.new("StringValue",playerToGiftName:FindFirstChild("OtherStats"):FindFirstChild("Gamepasses"))

	MPS.PromptProductPurchaseFinished:Connect(giftPurchaseFinished)
	remotes.GiftRemote.OnServerEvent:Connect(function(playerGifting, playetToGift)
		if playerGifting:FindFirstChild("OtherStats"):FindFirstChild("GiftTo") then
			local GiftToID = game.Players:GetUserIdFromNameAsync(playetToGift)
			playerGifting.OtherStats.GiftTo.Value = GiftToID
		end
	end)
end

It says this line is erroring:

local playerToGift = playerName:FindFirstChild("OtherStats"):FindFirstChild("GiftTo").Value

It says it can’t index a number with FindFirstChild, also the print isnt printing anything i dont know if thats related or not

You might try using the lua debugger to step through your code line-by-line and see that the variables are all what you expect.

I can only test this in an actual game not studio sadly, since it is gifting another player a gamepass and the player I am testing is not part of the teamcreate
