How to make a clone of tool and then put it into player backpack?

I am trying to make a shop gui and one of the items is Grappling Hook. I have this script there are no errors but yet when I test it in studio it does not give me the grappling hook. I do have enough coins too when I test it. Here is the script.

local coins = script.Parent.Coins

for i, v in pairs(script.Parent.Frame:GetChildren()) do -- i got this idea from berezaa and yes it does work
	if v:IsA("TextButton" or "ImageButton") then
		v.MouseButton1Click:connect(function()
			if v.Name == "GrapplingHook" then -- these are the parts I'm concerned about
				if coins.Value > 349 then
					coins.Value = coins.Value - 350
					local clone = game.Lighting.GrapplingGun:Clone()
					clone.Parent = game.Players.LocalPlayer.Backpack
				end
			end
		end)
	end
end
