Door not opening and closing correctly?

okay this is the problem, in this script it works perfectly but when it rotates, sometimes it goes over 359 ( so it makes it into 0 ) and sometimes when it goes past 0 it goes to (359)

so what i tried doing was making it so it closed almost all the way through but i dont like how it looks like in the game. How could i fix my script so it goes exact. I know i could use slerp but i failed at using slerp and rotatearound at the same time.

     var smooth = 2.0;
 var DoorOpenAngle = 85.0;
 var DoorCloseAngle = 0.0;
 var startPosition = 0;
 var open : boolean;
 var rotateAround : Transform;
 
 function Start(){
 
 startPosition = transform.eulerAngles.y;
 if(transform.eulerAngles.y > 264 && transform.eulerAngles.y < 300){
 transform.eulerAngles.y = 265;
 startPosition = 265;
 }
 if(transform.eulerAngles.y > 300){
 transform.eulerAngles.y = 0;
 startPosition = 0;
 }
 
 
 }
 
 //Main function
 function Update (){
 
  if(open == true){
   //var target = Quaternion.Euler (0, DoorOpenAngle, 0);
   // Dampen towards the target rotation
   //transform.localRotation = Quaternion.Slerp(transform.localRotation, target,
   //Time.deltaTime * smooth);
   if(rotateAround.transform.eulerAngles.y < DoorOpenAngle + startPosition){
   transform.RotateAround (rotateAround.position, Vector3.up, Time.deltaTime * smooth);
   }
  }
 
  if(open == false){
  // var target1 = Quaternion.Euler (0, DoorCloseAngle, 0);
   // Dampen towards the target rotation
   if(transform.eulerAngles.y > 3 + DoorCloseAngle + startPosition){
   transform.RotateAround (rotateAround.position, Vector3.up, Time.deltaTime * -smooth);
   //transform.localRotation = Quaternion.Slerp(transform.localRotation, target1,
  // Time.deltaTime * smooth);
  }
  }
 
 }
 
 
 //Activate the Main function when player is near the door
 function activate(){
 
 if(open){
 open = false;
 }else{
 open = true;
 }
 
 }
