I have tried doing what it says but it did not do anything. UnityException: Input Axis horizontal is not setup.
To change the input settings use: Edit → Project Settings → Input
NewBehaviourScript1.Update () (at Assets/NewBehaviourScript1.js:5)

On line 5 of NewBehaviourScript1,js, replace

Input.GetAxis("horizontal")

with

Input.GetAxis("Horizontal")
