Smooth camera script looking at left hand side of character.

The smooth follow camera script is working and following correctly. However, it is looking at the target from the left-hand side rather than the back of the target. Any help or workarounds would be appreciated. Thanks using UnityEngine; using System.Collections;

 public class R4Wing_SmoothFollowCam : MonoBehaviour {
 
     public Transform target;
     public float distance;
     public float height;
     public float heightDamping;
     public float rotationDamping;
 
     void LateUpdate () {
         if (!target) {
             return;
         }
 
         float wantedRotationAngle = target.eulerAngles.y;
         float wantedHeight = target.position.y + height;
         float currentRotationAngle = transform.eulerAngles.y;
         float currentHeight = transform.position.y;
 
         currentRotationAngle = Mathf.LerpAngle (currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
         currentHeight = Mathf.Lerp (currentHeight, wantedHeight, heightDamping * Time.deltaTime);
         Quaternion currentRotation = Quaternion.Euler (0, currentRotationAngle, 0);
 
         transform.position = target.position;
         transform.position -= currentRotation * Vector3.forward * distance;
 
         transform.position = new Vector3 (transform.position.x, currentHeight, transform.position.z);
         transform.LookAt (target);
 
     }
 }
