Mouse click object unity 5.3 UI?

Question

I'm currently working on a project that is due Monday for school. I've been working on it for a while, but when it comes to coding I always unable to solve any errors since I'm practically a beginner. How should I format my code so every time I click an object GUI appears? I'm currently using Unity version 5.3.

Code:

#pragma strict

 var scanners : UIText //variable for GUI text

 function Start () //scanner not clicked

 {
     scanners.enabled=false;
}

 function OnMouseDown() //scanner clicked

 {
     scanners.enabled=true;
}

 function OnMouseUp() //scanner unclicked

 {

     scanners.enabled=false;
}

GUI elements are drawn inside the OnGUI() function. but this is an old way of doing things. Since Unity 5 you can just add a UI text element (rightclick hierarchy > UI > Text) or use the 3D Text , and then gameObject.SetActive(true/false); on that text when you run the OnMouseDown/Up() functions.
