My shop is working, but the items I'm purchasing are not. How do i fix that?

I made a shop that works. It takes your money and gives you an item, but the item doesn't work. (the item works when I use it without buying in shop)

This is the code: (i got it from a youtube tutorial) Zims is my money

local player = game.Players.LocalPlayer

script.Parent.MouseButton1Click:Connect(function(click)
	if player.leaderstats.Zims.Value >= 10 then
		player.leaderstats.Zims.Value = player.leaderstats.Zims.Value - 10
		
		game.ReplicatedStorage.Tools.Sword:Clone().Parent = player:WaitForChild("Backpack")
	end
end)

Thanks for helping!
