Instantiate isnt working for spawner class

Forgive me, I’ve found a few questions similar to this but all of the fixes have been rather semantic nuances. Im trying to spawn my ‘Enemy’ object, which is just a cube at the moment at 1 of 3 random spawn points in my scene.

using UnityEngine;
using System.Collections;

public class Spawner : MonoBehaviour {

    public GameObject Enemy;
    GameObject[] objs;
    int top;

    void Start()
    {
        objs = GameObject.FindGameObjectsWithTag("Spawn_Point");
        top = objs.Length;
        InvokeRepeating("CreateObject", 0.01f, 5.0f);
    }

    void CreateObject()
    {
        Instantiate(Enemy, objs[Random.Range(0,top)].GetComponent<Transform>().position, Quaternion.identity);
    }

    void Update () {
        Instantiate(Enemy, new Vector3(1, 2, 1), Quaternion.identity);
    }
}

Neither the CreateObject() or Update() functions create a new object. Even the basic code given in the instantiate documentation fails.

using UnityEngine;
using System.Collections;

public class TestInstantiate : MonoBehaviour {

        public GameObject prefab;

        void Start()
        {
        for (int i = 0; i < 10; i++)
               Instantiate(prefab, new Vector3(i * 2.0f, 0, 0), Quaternion.identity);
        }
    }

Heres a picture of my unity scene with the settings on my Enemy prefab.

Well, I feel stupid. I needed to apply the scripts to an object in my scene. Placing the scripts on the ground object activated the scripts and everything began working.
