How does this break my script?

		if #game.Players:GetChildren() == 1 then
			for i,v in pairs(game.Players:GetChildren()) do
				v.Character:MoveTo(game.Workspace.spawns:findFirstChild(i).Position)
				table.insert(alive,#alive+1,v)
				_G.game = true
				game.Workspace.Lighting.FingerLazers:clone().Parent = v.Backpack
				if v.Character.Humanoid.Health > 0 then
					track_death(v)
				else
					died(v)
				end
			end
			repeat wait(1) until done
			done = false
		else
		message = Instance.new("Message", game.Workspace)
		message.Text = "Too many players have left! Waiting for more to start the game..."
		wait(3)
		message:Destroy()
		end
	end
end

When-ever I put

game.Workspace.Lighting.FingerLazers:clone().Parent = v.Backpack

In the script, it doesn't give me the Finger Lazers like I want it to from lightning, and the game doesn't end.

When I remove that 1 line, everything works fine but I need the Finger Lazers ;/

I'm pretty sure Lighting isn't in Workspace.

Maybe you could try a quick local instead of doing it directly. For example:

local g = game.Lighting.FingerLasers:Clone()
g.Parent = v.Backpack -- Note, backpack has only one capital letter, this gets me a lot.

Table.insert must one use two arguments. You've put in 3. You could perhaps do:

table.insert(alive,{#alive+1,v})

And, where is track_death and all the other functions from, please tell me and what is in the function. Thanks! :)

because you didnt do a please on the end
