Spectating script; no output? Please help.

I have a spectating script I made, but after you click on it it just says "close" but nothing else works? Here's the script:

local camera = game.Workspace.CurrentCamera
local on = false
script.Parent.MouseButton1Down:connect(function()
	if on == false then
		for i,v in pairs(game.Players:GetPlayers()) do
			if v.InGame.Value == true then
				camera.CameraType = "Attach" 
				camera.CameraSubject = v.Character.Head
				script.Parent.Text = "Close"
				game.Players.LocalPlayer.PlayerGui.timer.Frame.Visible = false
				game.Players.LocalPlayer.PlayerGui.tp.TextButton.Visible = false
				game.Players.LocalPlayer.PlayerGui.spect.Frame.Visible = true
				on = true
			end
		end
	end
	
	if on == true then
		game.Players.LocalPlayer.PlayerGui.timer.Frame.Visible = true
		game.Players.LocalPlayer.PlayerGui.tp.TextButton.Visible = true
		game.Players.LocalPlayer.PlayerGui.spect.Frame.Visible = false
		camera.CameraType = "Custom"
		camera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid
	end
end)

This needs to be a local script in a player or character in order to get game.Workspace.CurrentCamera.

Based on the for i,v in pairs(game.Players:GetPlayers()) do It appears your trying to do this for every player, but you're only using 1 camera.

Try making this a local script in a Player, and have this script so that you can do this to LocalPlayers separately.
