error code please help me (ADJUST)

hello i have a problem i try to make my character jump but it tells me this NullReferenceException: Object reference not set to an instance of an object NewBehaviourScript.Update() (at Assets/scripts/playercontroller.cs:33) help me it would be with great pleasure I give you the code

EDIT: I guess the problem is that the Awake method is misspelled in your code, it should start with a capital ‘A’.
