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");
		}
    }
}

as @RudyTheDev already stated.

Line 15, you put:

player = GameObject.find ("Player");

You need to capitalize the “F” in find, “Find” is a method on GameObject, “find” is not

Line 15 Corrected:

player = GameObject.Find ("Player");

Line 17, arguments are seperated by comma’s, not freaking periods - Also you your spelling is incorrect for position(you put postion), this is incorrect:

distance = Vector3.Distance(player.transform.position. skelly.transform.postion);

Line 17 Corrected:

distance = Vector3.Distance(player.transform.position, skelly.transform.position);

MORE:

Line 26, your spelling of position is incorrect again:

skelly.transform.postion = Vector3.MoveTowards(skelly.transform.postion, player.transform.position);

Line 26 corrected:

skelly.transform.postion = Vector3.MoveTowards(skelly.transform.position, player.transform.position);

All of these errors you should have been able to fix yourself, i have no doubt the console gave enough information in these cases.

Edit: Also in the future, add all your code, i had to add the ending curly braces for your class, also format the damn thing, its the least you can do for free help.
