Please Help

Very confused , I do not understand that for an error
Targetting.cs(3,14):error CS1041: Identifier expected. Please tell me , where did I go wrong ?

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class Targetting : MonoBehaviour 
{
	public List<Transform> targets;

	// Use this for initialization
	void Start () 
	{
		targets = new List<Transform>();

		AddAllEnemies();
	}

	public void AddAllEnemies()
	{
		GameObject[] go = GameObject.FindGameObjectsWithTag("Enemy");

		foreach(GameObject enemy in go)
			AddTarget(enemy.transform);
	}

	public void AddTarget(Transform enemy)
	{
		targets.Add(enemy);
	}

	
	// Update is called once per frame
	void Update () {
	
	}
}

line #3 (which isn’t in the listing because the format is messed up) should read:

using System.Collections.Generic;

looks like you’ve got a rogue space…
