Snapping Objects At Runtime

Hi people, I am creating a game where I need an object to snap into position when I enter a trigger. I know the trigger works because I used the destroy command on it, and that worked fine.

When I drag my item in to the trigger and take my finger off the mouse button I would like it to snap to that pos/gameobject, If it is not in a trigger then I would like it to return to another point in the game world (a kind of item bar).

Anyway, here is the code I have tried and I know it will probably seem really obvious and silly of me to ask this...

 using UnityEngine;

using System.Collections;

public class SnapPeg : MonoBehaviour {

 public Transform holeTransform;
 
 public Transform pegTransform;

 // Use this for initialization
 void Start () {
 
 }
 
 // Update is called once per frame
 void Update () {
     
 }
 
 void OnTriggerEnter(Collider other)
 {
     pegTransform.transform.position = holeTransform.transform.position;
     //Destroy(peg);
 }

}

I hope someone can help and I would like to say a pre-thanks =]

Cas.
