Horizontal is not set up in unity 3.4.2 how do i fix this

Here is the error

UnityException: Input Axis Horizantal is not setup.
To change the input settings use: Edit → Project Settings → Input
MoveAround.Update () (at Assets/Scripts/MoveAround.js:10)

I was trying to make a move script and it does not work here is the move script

var speed = 3.0;
var rotateSpeed = 3.0;

function Update ()
{
var controller : CharacterController = GetComponent(CharacterController);

// Rotate around y - axis
transform.Rotate(0, Input.GetAxis (“Horizantal”) * rotateSpeed, 0);

//Move forward / backward
var forward = transform.TransformDirection(Vector3.forward);
var curSpeed = speed * Input.GetAxis (“Vertical”);
controller.SimpleMove(forward * curSpeed);
}

@script RequireComponent(CharacterController)

When reviewing scripting errors, the best thing to do is check your syntax first and spelling of static accessors.

“Horizantal” needs to be “Horizontal”

Go to Edit—> project settings---->Input----->Click the gear icon----->Reset
this will return it to its original state. therefore setting up vertical and horizontal again
