Sounds play fine until .InstantHit == false. How do I fix?

Trying to get some audio to play when a setting on a module script called "InstantHit" is changed to false. How ever in the main code, the sounds do not play if InstantHit is changed to false instead of true. Code from MAIN script below

if S.InstantHit then -- Tried putting "S.InstantHit == false" still does not play the sound and breaks the gun.
            local HitObj, HitPos = AdvRayCast(Main.CFrame.p, Direction, S.BulletRange)
            local HitHumanoid = nil
            local SoundPart1 = Instance.new("Part")
            SoundPart1.Transparency = 1
            SoundPart1.Anchored = true
            SoundPart1.CanCollide = false
            SoundPart1.CFrame = CFrame.new(HitPos)
            SoundPart1.Parent = game.Workspace

            local BulletHit = Instance.new("Sound")
            BulletHit.Pitch = 1
            local soundIndex = math.random( 1, #SoundIDs )
            BulletHit.SoundId = SoundIDs[soundIndex]
            BulletHit.Volume = 1.5
            BulletHit.Parent = SoundPart1
            BulletHit:Play()

            delay(1 / 20, function()
                SoundPart1:Destroy()
