I am having a problem with my 3d tdf enemy movement code. C#

Assets/Scripts/EnemyMovement.cs(4,14): error CS0101: The namespace global::' already contains a definition for Enemy’

This is the error I have founded when designing my tower defense game. I seem to have found nothing besides this one error appear so far. Here is the current state of my code.:

using UnityEngine;
using System.Collections;

public class Enemy : MonoBehaviour

public float speed = 10f;
public float smooth = 2f;

private Transform target;
private int wavepointIndex = 0;

private Object waypoint;

void Start()
    target = Waypoints.points[0];

    InvokeRepeating("nextWaypoint", 0f, 0.5f);

void Update()
    Vector3 dir = target.position - transform.position;
    transform.Translate(dir.normalized * speed * Time.deltaTime, Space.World);

    transform.rotation = Quaternion.Slerp(transform.rotation, target, Time.deltaTime * smooth);

    if (Vector3.Distance(transform.position, target.position) <= 0.4f)

void GetNextWaypoint()
    if (wavepointIndex >= Waypoints.points.Length - 1)

    target = Waypoints.points[wavepointIndex];


I think that my error is located within the first few lines of code. I could however be completely wrong.

Somewhere else in your project files there is a class called Enemy. Just rename it.
