Why this won't work?

local Aut1 = game.Workspace.Door.Aut1
local Aut2 = game.Workspace.Door.Aut2

function OnTouch(part)
 debounce = false
 local humanoid = part.Parent:findFirstChild("Humanoid")
 if Humanoid ~= nil then
  Aut1.Position = vector3.new(Aut1.Position.x, Aut1.Position.y, Aut1.Position.z+5)
  Aut2.Position = vector3.new(Aut1.Position.x, Aut2.Position.y, Aut2.Position.z-5)
  wait(5)
  Aut1.Position = vector3.new(Aut1.Position.x, Aut1.Position.y, Aut1.Position.z-5)
  Aut2.Position = vector3.new(Aut2.Position.x, Aut2.Position.y, Aut2.Position.z+5)
  print("The Script Works")
 end
end
