How to display gameobjects when i pause the game?

Ok, firstly i would like to tell you i'm struggling with this array command in javascript. I'm trying to create a script to pause the game, and once the game is paused, the script should display components in a few gameobjects which is held in an array. Look at my code, it says an error saying the variable 'i' already exists, but when i try to change it to something like 'j' nothing happens.

var obj : GameObject[]; var displayPauseObjects : boolean = false;

function Awake(){

 obj = GameObject.FindGameObjectsWithTag("PauseObjects");
     

}

function Update(){

 if(Input.GetButtonDown("Pause") && displayPauseObjects == false)
 {
     
     for(var i = 0; i < obj.length; i++){
         obj[i].GetComponent(GUITexture).enabled = true;
     }
             displayPauseObjects = true;
     
 }

     //The First Part Works fine! When i press the pause key the game object's GUI Texture 

//component gets displayed. But again to hide the components the code doesnt work.

 if(Input.GetButtonDown("Pause") && displayPauseObjects == true)
 {
     
     for(i = 0; i < obj.length; i++){
         obj[i].GetComponent(GUITexture).enabled = false;
     }
     displayPauseObjects = false;
 }
 

}
