Problem with Spawn points

I have spawn points around my scene and I’m looking to spawn a prefab from a randomly selected one, I have each of my spawn points tagged and reference it in the code, I’m trying to piece it together with another question I’m following but having no luck, this is what I have below:

using UnityEngine;
using System.Collections;

public class spawn : MonoBehaviour
	// Prefab to spawn
    public GameObject disc;

	//The time (in seconds) in which the new prefab will be destroyed
	public int destroyTime = 15;

	//The time it takes for the prefab to be spawned
	public float spawnTime = 5;

	//Keeps track of the current spawn time
	private float curSpawnTime = 5;

	Vector3[] spawnPoints;

	int endOfArray;

	void Start()

		GameObject objs = GameObject.FindGameObjectsWithTag("SpawnPoints");
		foreach(GameObject obj in objs)
			spawnPoints = objs.GetComponent<Transform>().position;
		endOfArray = spawnPoints.Length;
		InvokeRepeating ("Spawn", 0.01f, 10.0f);

	void Spawn()

But this is the error I’m getting:

Look at the error. Trying to convert GameObject to GameObject… then in your foreach loop you’re trying to loop through a single GameObject because that’s what [objs] is. FindObjectsWithTag returns an array like you want, but your trying to make it a single object.

GameObject[] objs = GameObject.FindGameObjectsWithTag("SpawnPoints") as GameObject[] ;

Edit :

You’re going to run into another problem after you fix that though…

get rid of your foreach loop and put this instead

spawnPoints = new Vector3[objs.Length] ;

for(int i = 0 ; i < objs.Length ; i++)
   spawnPoints _= objs*.transform.position ;*_
