Keep a constant maximum zoom distance when other scripts are preventing it?

I have a problem where I try to limit the zoom distance, but it wont work at all. It could be other scripts or the script is outdated itself. Feedback is appreciated.

game.Players.PlayerAdded:connect(function(player)
	wait(0.1)
	player.CameraMaxZoomDistance = 20 -- Change this to what distance do you want.
end)
