Why wont my scripted motors work in the animation editor? (Indentation fixed)

I've prepared a script that should create a series of joints between parts in order to form not only hips and shoulders, but elbows and knees as well. When I run the instance, the model sticks together correctly, however, When I try to select it with the animation editor , the output says, 'Animedit only supports Motor6D with Parent == Part0 or Part1' There is a part labeled HumanoidRootPart, I've tried inserting a humanoid or alternatively , an animation controller. Below is the code, as well as a link to the actual model. Thanks in advance for any help you can offer!
