Why does the 2D UFO tutorial the script for moving UFO say compile error CS0101?

I have followed the 2d UFO course, but despite re-checking the script for moving the UFO, it comes up with

. Any advice? (1st error message is fixed)

My code is this:
using UnityEngine;
using System.Collections;

public class CompletePlayerController : MonoBehaviour

private Rigidbody2D rb2d;

void Start()
    rb2d = GetComponent<Rigidbody2D>();

void FixedUpdate()
    float moveHorizontal = Input.GetAxis("Horizontal");

    float moveVertical = Input.GetAxis("Vertical");

    Vector2 movement = new Vector2(moveHorizontal, moveVertical);



You probably have two scripts with the same name.

Open both CompletePlayerController.cs and Playercontroller.cs file to check their names. Make sure each file is named correctly with class name.
