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);
         }
     }
