How do I make my enemy stop at specific waypoints?

Hello everyone, I am making a waypoint system for a game, and it's working exactly the way I want it to. The only issue is that I want my enemy to stop at specific waypoints. So far I have only got it stopping at the very first waypoint. Can you please help me out?

 var accel = 0.8;
 var inertia = 0.9;
 var speedLimit = 10.0;
 var minSpeed = 1.0;
 var stopTime = 1.0;
 private var currentSpeed = 0.0;
 private var functionState = 0;
 private var moveState : boolean;
 private var waypoint : Transform;
 var rotationDamping = 6.0;
 var smoothRotation = true;
 var waypoints : Transform[];
 private var WPindexPointer : int;
 private var x : int;
 
 function Start ()
 {
     functionState = 0;
 }
 function Update ()
 {
     if (functionState == 0)
     {
         Accell ();    
     }
     if (functionState == 1)
     {
            Slow ();
     }
     waypoint = waypoints[WPindexPointer];
 }
 function Accell ()
 {
     if (moveState == false)
     {
         moveState = true;
     }
     if (waypoint)
     {
         if (smoothRotation)
         {
             var rotation = Quaternion.LookRotation(waypoint.position - transform.position);
             transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * rotationDamping);
         }
     }
     currentSpeed = currentSpeed + accel * accel;
     transform.Translate (0,0,Time.deltaTime * currentSpeed);
     if (currentSpeed >= speedLimit)
     {
         currentSpeed = speedLimit;
     }
 }
 function OnTriggerEnter (myTrigger : Collider)
 {
     switch(myTrigger.gameObject.name)
     {
         case "trigger1":
             stopTime = 5.0;
             Debug.Log(stopTime);
             functionState = 1;
             WPindexPointer++;
             break;
         case "trigger3":
             stopTime = 2.0;
             Debug.Log(stopTime);
             functionState = 1;
             WPindexPointer++;
             break;
         default:
             stopTime = 3.0;
             Debug.Log(stopTime);
             functionState = 1;
             WPindexPointer++;
             break;
     }
     if (WPindexPointer >= waypoints.Length)
     {
         WPindexPointer = 0;
     }
 }
 function Slow ()
 {
     Debug.Log("I am in Slow()");
     
     moveState = false;
     Debug.Log("moveState = false");
     currentSpeed = currentSpeed * inertia;
     transform.Translate (0,0,Time.deltaTime * currentSpeed);
     if (currentSpeed <= minSpeed)
     {
         currentSpeed = 0.0;
         Debug.Log("Current speed is 0");
         Debug.Log(stopTime);
         yield WaitForSeconds (stopTime);
         Debug.Log("Stopped");
         functionState = 0;
         Debug.Log("Off I go again");
     }
 }

Also, I figured out it's not running the if(currentSpeed <= minSpeed) function except on the first trigger.
