Need help checking if an item slot is filled

Hello everybody, so I have an issue with some code my friend wrote. So my issue is figuring out how to activate a Power up once it has been stored into a slot, via a button press. I don’t necessarily know where to look and have looked at this code over and over to try to figure it out but I may just not be focusing in the right area. there is a piece of commented out code that i wrote to try to piece it together but im not sure that it is the right code.

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using Rewired;

public class TestController : MonoBehaviour {
	private PowerUp[] StoredPowerUps = new PowerUp[4];
	private int NumberStoredPowerUps = 0;
	public PowerUp ActivePowerUp;
	public bool IsShuffling = false;
	private float ShuffleTimeOut = 5f;
	private float CurrentTimer = 0f;
	public PowerUp[] ShuffleList;
	public Image ShuffleIcon;
	public float ShuffleDelay = 0.05f;
	public float CurrentShuffleDelay = 0f;
	private int ShuffleIndex = -1;
	[SerializeField]
	private int PlayerId;
	private Player player;
	
	
	// Use this for initialization
	void Start () {
		player = ReInput.players.GetPlayer (PlayerId);
	}
	
	// Update is called once per frame
	void Update () {
		
		if (IsShuffling) {
			if(ShuffleIndex == -1){
				ShuffleIndex = Random.Range(0,ShuffleList.Length);
			}
			CurrentShuffleDelay += Time.deltaTime;
			if(CurrentShuffleDelay >= ShuffleDelay){
				CurrentShuffleDelay = 0f;
				ShuffleIndex++;
				if(ShuffleIndex >= ShuffleList.Length){
					ShuffleIndex = 0;
				}
				ShuffleIcon.sprite = ShuffleList[ShuffleIndex].image;
			}
			CurrentTimer += Time.deltaTime;
			if(player.GetButton("StopPower") || CurrentTimer >= ShuffleTimeOut){
				IsShuffling = false;
				Debug.Log("S");
				if(ShuffleList[ShuffleIndex].autofire){
					ActivePowerUp = ShuffleList[ShuffleIndex];
					Debug.Log("Activated "+ActivePowerUp.name);
				}else{
					int StoredIndex = NumberStoredPowerUps++;
					if(StoredIndex < 4){
						StoredPowerUps[StoredIndex] = ShuffleList[ShuffleIndex];
						Debug.Log("Stored "+StoredPowerUps[StoredIndex].name+" in slot "+StoredIndex);
					}
				}
				ShuffleList = null;
				ShuffleIndex = -1;
				CurrentTimer = 0f;
				
			}
			/*
			if(player.GetButton("Power1") && StoredPowerUps[0]){
				ActivePowerUp = ShuffleList[ShuffleIndex];
				StoredPowerUps[StoredIndex] = ShuffleList[ShuffleIndex];
			}
			*/
		}				
	}

Nevermind everybody figured it out i was slightly correct with my commented out code but had to change a couple of things here is what i wrote for those interested:

//Begin use stored
		if(player.GetButton("Power1") && StoredPowerUps[0] != null){
			ActivePowerUp = StoredPowerUps[0];
			StoredPowerUps[0] = null;
			Debug.Log("Activated "+ActivePowerUp.name);
		}
		if(player.GetButton("Power2") && StoredPowerUps[1] != null){
			ActivePowerUp = StoredPowerUps[1];
			StoredPowerUps[1] = null;
			Debug.Log("Activated "+ActivePowerUp.name);
		}
		if(player.GetButton("Power3") && StoredPowerUps[2] != null){
			ActivePowerUp = StoredPowerUps[2];
			StoredPowerUps[2] = null;
			Debug.Log("Activated "+ActivePowerUp.name);
		}
		if(player.GetButton("Power4") && StoredPowerUps[3] != null){
			ActivePowerUp = StoredPowerUps[3];
			StoredPowerUps[3] = null;
			Debug.Log("Activated "+ActivePowerUp.name);
		}
//End Use Stored
