Need help I am a Super Noob, I don't know code so well, I can't get my character to Jump.

Something isn’t quite right about your code formatting tags so your code is tough to read. They need to be in square brackets to work.

How to use code tags: Using code tags properly

For this particular class of problem, which could be scene/prefab setup and not even be in the code at all, I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

  • is this code even running? which parts are running? how often does it run?
  • what are the values of the variables involved? Are they initialized?

Knowing this information will help you reason about the behavior you are seeing.
