Voice Activated Lighting Script Issues?

So I'm trying to make it so when I chat a certain number, it changes the lighting, but when I do it does nothing. I know the script works, it's just this part:

		game.Lighting.Ambient = 169, 164, 155
		game.Lighting.Brightness = 2
		game.Lighting.OutdoorAmbient = 169, 151, 43
		game.Lighting.ShadowSoftness = 0.5
		game.Lighting.ClockTime = -16.001
		game.Lighting.GeographicLatitude = 52.692
		game.Lighting.FogColor = 121, 75, 35

Full Script if you Need it:

function onChatted(msg, recipient, speaker) 

local source = string.lower(speaker.Name) 
msg = string.lower(msg)

	if (msg == "/e 123984398450954") then 
		game.Lighting.Ambient = 169, 164, 155
		game.Lighting.Brightness = 2
		game.Lighting.OutdoorAmbient = 169, 151, 43
		game.Lighting.ShadowSoftness = 0.5
		game.Lighting.ClockTime = -16.001
		game.Lighting.GeographicLatitude = 52.692
		game.Lighting.FogColor = 121, 75, 35
	end 

end 

function onPlayerEntered(newPlayer) 
newPlayer.Chatted:connect(function(msg, recipient) onChatted(msg, recipient, newPlayer) end) 
end 

game.Players.ChildAdded:connect(onPlayerEntered)
