I know this isn't really considered "scripting", but I need help with it. -- Animation?

I want to animate a person with a backpack, but I'm really confused on how Motor6D's work in the animating process. I'm using the regular roblox animation system and I've tried so many times to get it to work, but as you can probably tell I've failed. Anyone willing to teach me?

I made a morph and it has the same exact backpack and placement on the character as the testing dummy. Help? ;c
