Player is a Nil Value?

This is a regular script, inside a TextButton, inside a frame, inside another frame, inside a SurfaceGui.

bin.MouseButton1Click:connect(function(player)
	if player.Name == bin.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Owner.Value then
		bin.Parent.Parent.Parent.Click:Play()
		if toggle == true then
			toggle = false
			bin.Style = Enum.ButtonStyle.RobloxRoundButton
			bin.TextColor3 = Color3.new(0/255, 0/255, 0/255)
			bin.Text = "Allow Visitors: Off"
		else
			toggle = true
			bin.Style = Enum.ButtonStyle.RobloxRoundDefaultButton
			bin.TextColor3 = Color3.new(255/255, 255/255, 255/255)
			bin.Text = "Allow Visitors: On"
		end
	end
end)

The output says: Workspace.Kiosk.Screen.Screen.Screen.Frame.Frame.Button.Scr:5: attempt to index local 'player' (a nil value)

Not sure why it says player is a nil value with the player parameter. Any help?

"Player" is not what you think it will be. Just putting "player" is just a variable representing something. To know what that something is, do print(player). You should be using a Local Script so you can go to the character easily by doing game.Players.LocalPlayer. You're working with a GUI so it's actually the best idea to use a Local Script. This will also cut down on all those nasty "Parents" you have.
