Why isn't Motor6D working properly?

It works fine with the first script but not the second script,why? The problem with the second script is that it won't move but the property changes. Please show how you managed to fix it.

First Script:

------------Vairbles-------------
local Group = Instance.new("Model",game.Workspace)
        script.Parent = Group
---------------------------------
local Part = Instance.new("Part",game.Workspace)
    Part.Position = Vector3.new(-12, 0.59, -24)
    Part.Parent = Group
---------------------------------
local Part1 = Instance.new("Part",game.Workspace)
    Part1.Name = "Part1"
    Part1.Parent = Group
-------------------------------------
local Motor = Instance.new("Motor6D",Part1)
--Changing Motor6D's Part Property---
        Motor.Part0 = Part
    Motor.Part1 = Part1
-------------------------------------
    wait(1)
    print("Now!")
    Motor.DesiredAngle = -1
    Motor.MaxVelocity = .1

Second Script:

------------Vairbles-------------
local Part = script.Parent.Part
local Part1 = script.Parent.Part1
local Motor = Instance.new("Motor6D",Part1)
--Changing Motor6D's Part Property---
        Motor.Part0 = Part
    Motor.Part1 = Part1
-------------------------------------
    wait(1)
    print("Now!")
    Motor.DesiredAngle = -1
    Motor.MaxVelocity = .1

The Second Script is set up like this: http://tinyurl.com/kmjcn6c
