Array problem, I'm novice

`Hi, I'm trying to make array, I have a transform in game and I want to make array with my prefabs and then when I press button, these prefabs will create as child of the my transform. Please post sample code. Thank you. I tried something but it didn't work. I was looking at unity scripts, but I don't understand how can I make what I want.

 public GameObject[] videos;
     public int numberOfVideos = 5;
 
     public string nameOfVideo;
 
 
     public GameObject video;
 
     // Use this for initialization
     void Start () {
         rs = GetComponent<RecordingSys> ();
         videos = new GameObject[numberOfVideos];
     }
     
     // Update is called once per frame
     void Update () {
         for (int i = 0; i < numberOfVideos; i++) {
             GameObject go = Instantiate (video, new Vector3 ((float)i, 1, 0), Quaternion.identity) as GameObject;
             go.transform.localScale = Vector3.one;
             go.transform.parent = GameObject.Find ("VideoPanel2").transform;
             videos[i] = go;
         }
