This won't loop?

tub=script.Parent
button=tub.button
smoke=tub.smoke
smokes={smoke.Part,smoke.Part1,smoke.Part2,smoke.Part3}

debounce=true
print("Loaded: ",script.Name)
print("Made a ClickDetector.. in ",button.Name)

button.ClickDetector.MouseClick:connect(function()
    if debounce==true then
    debounce=false
    if button.ClickDetector~=nil then
    print("Making Smoke in all Parts specified")
    w1=Instance.new("Smoke",smokes[1])
    w1.Opacity=0.1
    w1.RiseVelocity=2
    --
    w2=Instance.new("Smoke",smokes[2])
    w2.Opacity=0.1
    w2.RiseVelocity=2
    --
    w3=Instance.new("Smoke",smokes[3])
    w3.Opacity=0.1
    w3.RiseVelocity=2
    --
    w4=Instance.new("Smoke",smokes[4])
    w4.Opacity=0.1
    w4.RiseVelocity=2
    print("Made smoke on all Parts specified")
    --
    tub.button.ClickDetector:Destroy()
    end
    debounce=true
    print("Made a new ClickDetector and removed the previous one")
    q=Instance.new("ClickDetector",tub.button)
    q.Name="omgNightstopHackingme"
    print("Renamed the current ClickDetector to: ",q.Name)
    button.omgNightstopHackingme.MouseClick:connect(function()
        if debounce==true then
            debounce=false
        smoke.Part.Smoke:Destroy()
        smoke.Part1.Smoke:Destroy()
        smoke.Part2.Smoke:Destroy()
        smoke.Part3.Smoke:Destroy()
        print("Destroyed all Smoke. Waiting 3 seconds")
        wait(3)
        q:Destroy()
        print("Destroyed ",q.Name,", Now waiting 5 seconds until debounce is True")
        wait(5)
        end
        debounce=true
    end)
    end
    debounce=true
    Instance.new("ClickDetector",button)
    print("Made a new ClickDetector in ",button.Name)
end)

Sorry about all the prints, It's for debugging. I'm trying to figure out how to make the ClickDetector clickable again when the script ends, so you can repeat the function(s). Help would be appreciated!
