change arrow keys to move and jump help

The following code gets him to move left and right but it uses the "up and down" arrow keys. How do I change it so it uses the "right and left" arrow keys instead? How do I make him jump?

Code (CSharp):

1. public float spead;
2. private Rigidbody2D rb;
3.  
4. void Start()
5.     {
6.         rb = GetComponent<Rigidbody2D>();
7.     }
8.  
9.     private void FixedUpdate()
10.     {
11.         float h = Input.GetAxis("Horizontal") * 5;
12.         float v = Input.GetAxis("Vertical") * 5;
13.  
14.         Vector3 vel = rb.velocity;
15.         vel.x = h;
16.         vel.x = v;
17.         rb.velocity = vel;
18.  
19.      
20.  
21.     }
22.  
23. }
24.  

 

Code (CSharp):

1. vel.x = h;
2. vel.x = v;

Something here is wrong. See if you can spot it

 

I did it a different way but having more than one way of doing it is nice

 

Perhaps you missed my point

Code (CSharp):

1.     vel.x =
2.     vel.x =

 

You must modify the default input in Edit/Project Settings/Input: https://docs.unity3d.com/Manual/class-InputManager.html
