How do I add a Motor6D to a custom model?

Ill be brief, I need a new script for my custom model custom model (with a humanoid part) but it is not working.

Here is the code I was using:

Motor6D.Part0 = HumanoidRootpart, Motor6D.Part1 = torso, Motor6D.Part1 = Right arm,
Motor6D.Part1 = Left arm, Motor6D.Part1 = Right leg, Motor6D.Part1 = Left leg.

(Remember I am a noob at scripting so please don't be mean).

Thank you for your attention.
