Missing definitions and script error

This script makes an animated AI wander around a game object, however the console is displaying these errors and i have no idea how to fix them.

Here's the script using UnityEngine; using System.Collections;

 public class RandomWander : MonoBehaviour {
 
     public GameObject init;
     private Transform initpos;
     private float time = 10;
     private bool update = true;
      public float radius;
     Animator anim;
     float lowX;
     float highX;
     float lowZ;
     float highZ;
     
     // Use this for initialization
     void Awake () {
         anim = gameObject.GetComponent <Animator>();
         initpos = init.GetComponent<Transform>();
            lowX = initpos.x - radius;
            highX = initpos.x + radius;
            lowZ = initpos.z - radius;
            highZ = initpos.z + radius;
     }
     
     // Update is called once per frame
     void Update () {
         if (update) {
             Vector3 pos = getRandomPos();
         }
         
         gameObject.LookAt(pos);
         
         if (gameObject.transform.position == pos){
             time -= Time.deltaTime;
             anim.SetBool("Walking", false);
             if (time <= 0.0f){
                 update = true;
                 time = 10.0f;
             }
         } else {
             transform.position += transform.forward * 0.2f;
             anim.SetBool("Walking", true);
         }
     }
     
     Vector3 getRandomPos(){
         Vector3 pos;
         pos.x = Random.Range(lowX, highX);
         pos.y = initpos.y;
         pos.z = Random.Range(lowZ, highZ);
         return pos;
     }
 }
 

If anyone can resolve these issues it would be greatly appreciated.
