How would I fix this?

I made a Custom Character Script already and placed the CustomCharacter into ServerStorage but when the customcharacter is loaded it goes okay until I try to move him he doesn't move his body just rotates when I mouselock and move my mouse. What would I add to the model to make the character moveable and controllable?

More information would be necessary, screenshots, a piece of broken code, errors if any. Your question is confusing :s
