Sounds cannot be heard ? NEED HELP

	if FireSound then
	ff = Instance.new("Sound")
	bb = Instance.new("Sound")
	bb.SoundId =''-- bullet 
	ff.SoundId ='' -- fire
	bb.Volume = 1
	ff.Volume = 1
	bb.Pitch = 0.8
	ff.Pitch = 1
	bb.Parent = script.Parent.A1
	ff.Parent = script.Parent.Main
	bb:Play()	
	ff:Play()

Basically these are from my gun, when u shoot it emits sounds from special parts, but my ff and bb are marked as blue ~~~~ lines, also my friend cannot hear these sounds when i shoot ?? whats the prob

P.s i removed the sounds so people don't take them

PLS people help me ;-;

I already know that its a localscript causing this but i don't know how to fix it ? so someone pls ???

Ensure the script is not a localscript. That's my guess.
