Button doesn't show up in pause

The pause function works but there is no button while paused.

 var paused : boolean = false;
 
 
 function Update () {
 
 
 
     if(Input.GetKeyDown(KeyCode.Escape) && paused == false)
    {
    
    paused = true;
        if (GUI.Button(new Rect(10, 10, 200, 50), "Disconnect"))
        {
            Application.LoadLevel("MainMenu");
            Network.Disconnect();
        }
    
    Time.timeScale = 0;
    
    
    
    }
    else if(Input.GetKeyDown(KeyCode.Escape) && paused == true) {
    
    
    paused = false;
    
    
    Time.timeScale = 1;
    
    }
     
     
 
 }
