Can you help me with Sound?

Hello, I currently have this script that plays Sound that is in its parent.

script.Parent.Sound2:Play()
                                         						wait(2)   	

I was wondering how I could make this only play once through a script instead of repeating as the WHOLE repeats when the function is activated?

Script I have it in:

objects = {}
teamcolor = BrickColor.new(script.Parent.Name)
config = script.Parent.Parent.Parent.Configuration
wait(1)

script.Parent.Essentials.Spawn.TeamColor = teamcolor
script.Parent.Essentials.Spawn.BrickColor = teamcolor

script.Parent.Essentials.Collector.Touched:connect(function(hit)
    if hit:FindFirstChild("Cash") then
        script.Parent.Cash.Value = script.Parent.Cash.Value + hit.Cash.Value
        Instance.new("Sparkles",hit).Color=Color3.new(math.random(1,255)/255,math.random(1,255)/255,math.random(1,255)/255)
        game.Debris:AddItem(hit,0.1)
    end
end)


script.Parent.Essentials.Giver.Touched:connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player ~= nil then
        if script.Parent.Owner.Value == player then
            if hit.Parent:FindFirstChild("Humanoid") then
                if hit.Parent.Humanoid.Health > 0 then
                    local cashmoney = game.ServerStorage.MoneyStorage:FindFirstChild(player.Name)
                    if cashmoney ~= nil then 
                        cashmoney.Value = cashmoney.Value + script.Parent.Cash.Value
                        script.Parent.Cash.Value = 0
					end
                end
            end
        end
    end
end)

script.Parent:WaitForChild("Buttons")
for i,v in pairs(script.Parent.Buttons:GetChildren()) do
    if v:FindFirstChild("Head") then

        local object = script.Parent.Purchases:FindFirstChild(v.Object.Value)
        if object ~= nil then
            objects[object.Name] = object:Clone()
            object:Destroy()

        end

            v.Head.CanCollide = false
            v.Head.Transparency = 1
            coroutine.resume(coroutine.create(function()
                if script.Parent.PurchasedObjects:WaitForChild(v.Dependency.Value) then
                    if config.ButtonFadeInDependency.Value == true then
                        for i=1,20 do
                            wait(config.ButtonFadeInTime.Value/20)

You should have the Sounds out of the script and where you activate the functions.
