How do I fix a script that works in studio but not ingame? I've done everything possible to fix it.

So I'm trying to make a game and in the spawn I want characters that appear to be singing to the music, which I already have a script for. while true do wait(0.001) script.Parent.Scale = Vector3.new(script.Parent.Scale.X, script.Parent.Parent.Parent.Sound.PlaybackLoudness / 215, script.Parent.Scale.Z) end

The script works completely fine in Studio but when I go to use it in online it doesn't work, I've tried using localscripts, disabling FE, and doing virtually everything possible. Is there something I'm doing wrong?
