my ladder script not working plz help me

Hello everybody i not good at c# but i tried some scripting with script api.I tried to make a ladder system with vector3 up ,and ontriggerstay but not worked.i put a video u can learn better with video and that is my codes

using UnityEngine;
using System.Collections;

public class Merdiven : MonoBehaviour
{

void OnTriggerStay(Collider other)
{
    transform.position += Vector3.up * Time.deltaTime;
}

}link text

As visible in the video, you’re chaning the position of the ladder instead of the player. So try this:

 void OnTriggerStay(Collider other)
 {
     other.gameObject.transform.position += Vector3.up * Time.deltaTime;
 }
