Why won't this clone?

I made this really simple script, but it's not working.

local backpack = game.Players.LocalPlayer.BackPack
script.Parent.Touched:connect(function()
	game.Lighting.Sword:Clone(backpack)
end)

Help?

You have to set the parent;

game.Lighting.Sword:Clone().Parent = backpack

local backpack = game.Players.LocalPlayer.Backpack
script.Parent.Touched:connect(function()
    modelcopy=game.Lighting.Sword:Clone()

modelcopy.Parent=backpack
end)

local backpack = game:service("Players").LocalPlayer.Backpack
--script.Parent.Touched:connect(function()
game:service("Lighting"):FindFirstChild("Sword"):Clone().Parent=backpack
--end)

Try this. Make sure you put it in the part that gives the sword.

local sword = game.Lighting.Sword
script.Parent.Touched:connect(function(h)
    local player = game.Players:GetPlayerFromCharacter(h.Parent) -- find the player from the character

	if (player) then
		-- a player touched it
		
		local clone = sword:Clone()
		clone.Parent = player.Backpack -- parent the clone to the player's backpack
	end
end)

script.Parent.Touched:connect(function(p)
	p = game.Players:GetPlayerFromCharacter(p.Parent)
	if p then
		game.Lighting.Sword:Clone().Parent = p.Backpack
	end
end)

There you go!
