Gamepass GUI doesn't give sword?

This doesn't seem to work. I've changed so many things, and it still doesn't work. I've spent hours on this. Can anyone help me find out what's wrong?

ID = 162597573
GPS = game:GetService("MarketplaceService")
player = script.Parent.Parent.Parent.Parent.Parent

function Buy()
	game:GetService("MarketplaceService"):PromptPurchase(player,ID)
	GPS.PromptPurchaseFinished:connect(function(player, ID, isPurchased)
		if isPurchased then
			clone1 = game.ServerStorage["Dual Darkheart"]:clone()
			clone1.Parent = player.Backpack
		end
	end)
end

script.Parent.MouseButton1Click:connect(Buy)

local passid = 000000000 -- Gamepass ID --
local tools = {""} -- Tool names EXACTLY, make sure the tools are in Lighting --
local GamePassService = Game:GetService('GamePassService')
game.Players.PlayerAdded:connect(function(player)
repeat wait(0) until player.Backpack	
repeat wait(0) until player.StarterGear
if GamePassService:PlayerHasPass(player, passid) then
for i = 1,#tools do
game.Lighting:FindFirstChild(tools[i]):Clone().Parent = player.Backpack
game.Lighting:FindFirstChild(tools[i]):Clone().Parent = player.StarterGear
end
end
end)

Try that? You have to set it up (For in-game purchase) (Put tools in lighting.)
