How to get chunks to the right position

I can generate chunks, and perlin noise, but for some reason my terrain doesent position correctly, any help.

chunk cretor code

using UnityEngine; using System.Collections;

public class ChunkCreator : MonoBehaviour {

 public GameObject chunck;
 public int amount = 5;
 public int Size = 16;
 public float Scale = 7.00f;
 public float ScaleModifier = 5.00f;
 public float OffSetHeight = 7f;
 public Vector3 Pos = new Vector3 (0, 0, 0);
 // Use this for initialization
     void Start () 
     {
     for(float X = transform.position.z; X < amount; X++)
         {
         Pos.x = X * Size;
         for(float Z = transform.position.z; Z < amount; Z++)
             {
                 Pos.z = Z*Size;
                 GameObject C = Instantiate(chunck, Pos, Quaternion.identity) as GameObject;
                 C.transform.parent = transform;
                 C.transform.position = Pos;
             Debug.Log("Chunck at:"+Pos);
             }
         }
     foreach (Transform Child in transform) {
         Debug.Log ("Real pos" + transform.position);

             
     }
     }
     



 }

outputs: Chunk at:0,0 Chunk at:16,0 Chunk at:0,16 Chunk at:16,16 Real Pos: 0,0 Real Pos: 0,0 Real Pos: 0,0 Real Pos: 0,0

Why?
