Why isn't this debounce working?

I made a debounce that stops the Part from turning transparent if touched then once and then turn visible if it's done being touched,but it won't turn visible,why? Please show how you managed to fix it.

local Part = script.Parent
Touched = false
-----------------------------
    Part.Touched:connect(function(TouchedPart)
        Touched = true
        FoundHumanoid= TouchedPart.Parent:FindFirstChild("Humanoid")--Checks if it's a humanoid
        -----------------------------
                if not FoundHumanoid then
                    print("You're not a Character "..TouchedPart.Name.." !")
                else
                if not Touched then -- If not touched
                -----------------------------
                    Part.TouchEnded:connect(function(TouchEnd)--If the touch has ended then do the following
                    print("I haven't been touched!")
                        Part.Transparency = 0
                            Touched = false
                       end)
                    -----------------------------
                    else--If it's still touched then do the following
                         Part.Transparency = 0.5
                         print("I've been touched")
                        Touched = false

                      end 
                    end
                  end)
