What parsing errors do i have

it is in C sharp code starts now:

 using UnityEngine;
 using System.Collections;
 
 public class Skellyattack : MonoBehaviour {
     public GameObject player;
     public GameObject skelly;
     public float distance;
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         player = GameObject.find ("Player");
         skelly = GameObject.Find ("skeleton");
         distance = Vector3.Distance(player.transform.position. skelly.transform.postion);
 
         if (distance <= 3) {
             skelly.animation.CrossFadeQueued("run", 0.3f, QueueMode.PlayNow);
         }
         else if(distance < 15 && Distance > 5.0f){
             skelly.animation.CrossFadeQueued("attack", 0.3f. QueueMode.PlayNow);
             skelly.animation.CrossFade("run");
             skelly.transform.LookAt(player.transform.position);
             skelly.transform.postion = Vector3.MoveTowards(skelly.transform.postion, player.transform.position);
         }
         else
         {
             skelly.CrossFadeQueued("run", 0.3f, QueueMode.PlayNow);
             skelly.CrossFade("idle");
         }
     }
 }
