Trying to delay movement of a GameObject

Hi guys,

I have a scene made with NGUI where I have four panels, each with a different comic drawing. Each one has the following script attached:

 var start : Transform;
 var end : Transform;
 
 var delay : float = 0;
 var duration : float = 2;
 
 private var myTransform : Transform;
 
 private var startPoint : Vector3;
 private var endPoint : Vector3;
 
 private var startTime : float;
 private var elapsedTime : float = 0;
 
 
 function Start () {
 
     myTransform =  transform;
     myTransform.position = start.position;
     
     startPoint = start.position;
     endPoint = end.position;
     
     startTime = Time.time;
 
 }
 
 function Update () {
 
     elapsedTime += Time.deltaTime;
     
     if(elapsedTime >= delay)
     {
         myTransform.position = Vector3.Lerp(startPoint, endPoint, (Time.time - startTime) / duration);
     }
 
 }

All of the panels have the same duration of 2 seconds, with each panel having a delay of, from first through fourth, 0, 3, 6, and 9 seconds, respectively. The problem is that when their delay timers run out, they just pop randomly into their target destinations instead of transitioning smoothly from the designated starting point. Is there another way to smoothly move a GameObject from one point to another and do so with a delay?
