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);
