Why isnt the last bit of code executing?

So this script works PERFECTLY fine, until the last bit of code. Anything written behind line 26 won't execute. The output shows no errors, It just doesnt do anything. So basically I just want the last bit to execute when the for statement over it has changed each brick's transparency to 0.

allmehtraps = game.Workspace.traps
a = {allmehtraps.Part1,allmehtraps.Part2,allmehtraps.Part3,allmehtraps.Part4}
butt = script.Parent

script.Parent.ClickDetector.MouseClick:connect(function()
    butt.BrickColor = BrickColor.new("Really red")
            butt.ClickDetector:Destroy()
    for i,v in pairs(a) do
        for i = 0,1, 0.1 do
            wait(.15)
            v.Transparency = i
            if v.Transparency == 1 then 
                v.CanCollide = false
                end
        end

    end
    wait(20)
    for i,v in pairs(a) do
        if v.CanCollide == false then

            for i = 1,0, -0.1 do
                wait(.075)
                v.Transparency = i
            end
                if v.Transparency == 0 then
                v.CanCollide = true
                butt.BrickColor = BrickColor.new("Bright green")
                lol = Instance.new("ClickDetector",script.Parent)
            end
        end
    end
end)
