How to make a click detector play a sound when clicked?

This is the script:

game.Workspace.clickdetectorevent.OnServerEvent:Connect(function()
    local button = script.Parent.Parent.Model.Button
    local door = script.Parent.Parent.Door

    button.BrickColor = BrickColor.Black()
    button.Transparency = 0.5
    door.CanCollide = false
    door.Transparency = 0.6
    script.Parent.Parent.Model.Button.beep.play()
    wait(3)

    button.BrickColor = BrickColor.Red()
    button.Transparency = 0
    door.CanCollide = true
    door.Transparency = 0


end)

I'm very new to scripting, and I can't figure out how to play a sound (the sound is named beep) I'm sorry if there's some sort of obvious error, like I stated before, I'm very new and any piece of advice or help is greatly appreciated.
