How do I to turn off items on a button click

Not sure what's going on here but I just want to be able to switch between things being on or off as I click on a button.


using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class InputTest : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
public GameObject[] objects;
public int activeIndex = 0;
public int aIndex;

if (OVRInput.Get(OVRInput.Button.One))
{
activeIndex = aIndex;
for (int i = 0; i < objects.Length; i++)
objects.SetActive(i == activeIndex);
}

}
}
