Music won't play when player's stage value changes?

This is in a localscript in StarterCharacterScripts and has a numbervalue child

--script for playing music locally depending on player's stage value

if script.Stage.Value == 2 then
	game.Workspace.Music.Stage1:Stop()
	wait(0.2)
	game.Workspace.Music.Stage2:Play()
end

You need an Checker that checks all time not just one time so you can use:

local stage = script.Stage

while wait() do
if stage.Value == 2 then
workspace.Music.Stage1:Stop
wait(0.1)
workspace.Music.Stage2:Play()
end
end
