Why doesn't this script loop the sound?

Hello, please can someone tell me what I have done wrong with line 16? I want it to loop the above soundtrack 10 times but it only plays once.

This is the error message: Workspace.Part.Script:18: attempt to call global 'loop' (a nil value)

Thank you.

BoolValue = script.Parent.Parent.EmergencyLight1.Toggle
sound1=game.Workspace.Sound1
sound2=game.Workspace.Sound2
sound3=game.Workspace.Sound3
sound4=game.Workspace.Sound4 
 
function onClick()
    if BoolValue.Value == false then
        BoolValue.Value = true
        print(BoolValue.Value)
    sound1:Play()
wait(3)
sound2:Play()
wait(5)
sound3:Play()
loop(10) -- Why doesn't this loop? It just waits then plays the other sound
wait(85)
sound4:Play()
    else BoolValue.Value = false
    end
end
 
script.Parent.ClickDetector.MouseClick:connect(onClick)

You have never defined loop. (Hence it is nil; you are calling it with a value of 10; but you cannot call nil, hence your error).

Why would this do anything in particular?

Sounds do not have any API to play them a certain number of times. You can loop using the Looped property but this does not let you configure a number of loops. You must manage that yourself, by stopping it after a certain amount of time, e.g., 10 * lengthofsound seconds.

There is basicly no scripting to do it. You put on loop on the sound id. If you talking about something else please tell me.
