Moving Question

I get this error when following this mans tutorial named ETeeski. Does anyone know what the problem is. (i am new to J.S) This is the error.

Assets/PlayerMovementsScript.js(13,15): BCE0024: The type ‘UnityEngine.Input’ does not have a visible constructor that matches the argument list ‘(String)’.
here is my two scripts I am using.

var walkacceleration : float;
var cameraObject : GameObject;



function Update () 
{
transform.rotation = Quaternion.Euler
	(0, cameraObject.GetComponent
	(MouseLookScript).currentYRotation, 0);

rigidbody.AddRelativeForce(Input.GetAxis("Horizontal") * walkacceleration, 0, 
	 Input("Vertical") * walkacceleration);
}

and for mouse movement

var defaultCameraAngle : float = 60;
@HideInInspector
var currentTargetCameraAngle : float = 60;
@HideInInspector
var racioZoom : float = 1;
@HideInInspector
var racioZoomV : float;

var racioZoomSpeed : float = 0.2;
 
var lookSensitivity : float = 5;
@HideInInspector
var yRotation : float;
@HideInInspector
var xRotation : float;
@HideInInspector
var currentYRotation : float;
@HideInInspector
var currentXRotation : float;
@HideInInspector
var yRotationV : float;
@HideInInspector
var xRotationV : float;
var lookSmoothDamp : float = 0.1;
@HideInInspector
var currentAimRacio : float = 1;
 
function Update ()
{
    if (currentAimRacio == 1)
        racioZoom = Mathf.SmoothDamp(racioZoom, 1, racioZoomV, racioZoomSpeed);
    else
        racioZoom = Mathf.SmoothDamp(racioZoom, 0, racioZoomV, racioZoomSpeed);
       
    camera.fieldOfView = Mathf.Lerp(currentTargetCameraAngle, defaultCameraAngle, racioZoom);
 
    yRotation += Input.GetAxis("Mouse X") * lookSensitivity * currentAimRacio;
    xRotation -= Input.GetAxis("Mouse Y") * lookSensitivity * currentAimRacio;
   
    xRotation = Mathf.Clamp(xRotation, -90, 90);
   
    currentXRotation = Mathf.SmoothDamp(currentXRotation, xRotation, xRotationV, lookSmoothDamp);
    currentYRotation = Mathf.SmoothDamp(currentYRotation, yRotation, yRotationV, lookSmoothDamp);
   
    transform.rotation = Quaternion.Euler(currentXRotation, currentYRotation, 0);
}

Input(“Vertical”) should be Input.GetAxis(“Vertical”)
