Character Controller / Charactor Motor has no inputs?

I made a movement script using character controller, basically Input.GetButton(“j”), from what I understand “character motor” has gavity for jumping, so I set and input for jumping to the spacebar, attach the script to the player and also attach the CharacterMotor script to the player, Disabled all my other scripts,press space and nothing happens? I must be missing something, so I guess my question is:
How do you make the player jump with physics attaching the charactermotor script?

Try using Input.getKeyDown(KeyCode.J) check if this works. also are you using rigidbody? try to Debug.Log to check if the key input works. or make sure your input type is set to key/mouse button. if this still doesn’t work, post the code please.
