How to make an object go upward when button is click

This code is working well, but only one o object is moving upward when i click the button. How can i make that when i tap the button multiple objects will move upward?

using UnityEngine;
using System.Collections;

public class GUIscript : MonoBehaviour {

public GameObject objectToMove;

void OnGUI()
{
  if (GUI.Button(new Rect(10, 10, 150, 100), "Move The Cube"))
     {

//Option 1 using AddForce.
//objectToMove.rigidbody.AddForce(Vector3.up*10);

//Option 2 using transform.
//objectToMove.rigidbody.velocity = transform.up * 1;

//Option 3, this will move the object to the coordinates you enter in the Vector3 values.
//objectToMove.transform.position = new Vector3(0, +1, 0);

//Option 4, this might be your most ideal one to use.
//objectToMove.transform.Translate(Vector3.up * 2, Space.World);

     }

}

}

you can create an array of GameObjects that you’d like to move. Afterwards you can make a for loop (or a foreach loop) in order to move them all simultaniously:

public GameObject[] objectsToMove;

void OnGUI()
{
  if(GUI.Button(new Rect(10, 10, 150, 100), "Move The Cubes")
  {
     foreach(GameObject object in objectsToMove)
     {
        //Move object here using Option1
        object.rigidbody.AddForce(Vector3.up*10);
     }
  }
}
