Need help in creating a Pause Menu[Solved]

Hello guys this game is mainly focusing on Android platform, I have just joined yesterday and started making a game. Although I don't have any programming experience I will try my best to explain my script.

I have a Parent Object named "PauseGame" inside which there are 4 child objects with box colliders namely "PauseMenuBG,resume,exit,levellist"(which are imported images) and these are in a seperate Layer called "Interrupt" which is above default(in which game is being played) and background.

I am using the OnMouseDown function which needs a box collider for resume to work. However the box colliders are affecting the default game layer(images are not rendered but box colliders are still present).

May I know how to remove these colliders on resume button clicked ? And is there any other way to create the pause menu without box colliders?

My resume script is as follows :

 #pragma strict
 
 //perishMenu is for PauseGame parent object
 var perishMenu : GameObject;
 
 function OnMouseDown () {
   //resume game
   Time.timeScale = 1;
   //on click don't render this parent object
   var renderers =  perishMenu.GetComponentsInChildren.<Renderer>();
   
      for (var r : Renderer in renderers)
         {
             r.enabled = false;
         }
     }
 

Solved using my Pause Menu script (Answer :)

 #pragma strict
 
 var isPaused : boolean = false;
 var gameMenu : GameObject;
 var perishCollider : boolean = false;
 var playCollider : GameObject;
 var levelCollider : GameObject;
 var exitCollider : GameObject;
 
 function Start () {
 
        playCollider.collider2D.enabled = perishCollider;
        levelCollider.collider2D.enabled = perishCollider;
        exitCollider.collider2D.enabled = perishCollider;
           //At start don't show the pause menu
       var renderers =  gameMenu.GetComponentsInChildren.<Renderer>();
        for (var r : Renderer in renderers)
         {
             r.enabled = false;
         }
         
         //Always start the game even when exitted using the pause menu
         Time.timeScale = 1;
 
 }
 
 function OnMouseDown () {
    
    //create new variable for the same gameobject 
    var remrenderers =  gameMenu.GetComponentsInChildren.<Renderer>();
     
    //if clicked render pause menu 
    if(!isPaused) {
     
     playCollider.collider2D.enabled = !perishCollider;
     levelCollider.collider2D.enabled = !perishCollider;
     exitCollider.collider2D.enabled = !perishCollider;
     Time.timeScale = 0;
      
      //declare new instance of the pause menu
      for (var a : Renderer in remrenderers)
         {
             a.enabled = true;
         }
     }
     else {
     
     
 
      //don't render on any click(code for safety)
      for (var a : Renderer in remrenderers)
         {
             a.enabled = false;
         }
     
     
     }
    
    }
