Tryna make a sound like, once the first sound stops, I didnt loop, the second one starts playing?

    if script.Parent.Sound.IsntPlaying then

game.Workspace.Sound:Stop()

game.Workspace.Sound2:Play()

end

end)

(btw what im saying now isn't in the script, but the first "end" is red underscored)

IsntPlaying

Is not a property of a sound but you might want to use the event Sound.Ended This is an example of Sound.Ended:

local Sound = workspace.sound
local Sound2 = workspace.sound2

Sound:Play()

local function SoundEnded()
	Sound2:Play()
end

Sound.Ended:Connect(SoundEnded)
