I can't get Brick .Touched to work when i put a Part into a folder, can someone tell me what is up?

Here. I changed the event to only work if the part isn't equal to nil. I also added Debounce so that it dosen't just print loads of stuff at once. If you want to learn about Debounce go here: http://wiki.roblox.com/index.php?title=Debounce

local debounce = false
local NB = Instance.new("Part", game.Workspace)
NB.Size = Vector3.new(1,1,1)
NB.Position = Vector3.new(0,0,0)
NB.Anchored = false
NB.Name = "1"

print("Ok_1")

game.Workspace.PartFolder.ChildAdded:connect(function(Brick)
    if Brick then
        print("Ok_2")

        wait(1) 

        print(Brick.Name)

        Brick.Touched:connect(function(Thing)
            if not debounce then
                debounce = true
                print("Ok_3")
                print(Thing) 
                print("poop")
                wait(3) --changes this to how long you want the script to wait before it can print something again
                debounce = false
            end

        end)

    end

end)

local NB2 = Instance.new("Part", game.Workspace.PartFolder)
NB2.Size = Vector3.new(1,1,1)
NB2.Position = Vector3.new(0,2,0)
NB2.Anchored = false
NB2.Name = "2"
