disabling Mesh renderer on runtime.

I want to turn the mesh renderer off on runtime but for some reason the mesh renderer gets disabled but the object still can be seen; I tried turning the component itself off and also tried turning the renderer of (renderer.enable = false;)

Here is the script Im using, it disables the renderer depending of how far the Player is, I have a similar script for turning lights off that works perfectly

 using UnityEngine;
 using System.Collections;
 
 public class Betolder : MonoBehaviour {
     public float availableDistance;
     private float Distance;
 
     ///------------------------------
 
      
     // Update is called once per frame
     void Update () {
     GameObject Player = GameObject.FindGameObjectWithTag("Player");
     MeshRenderer MeshComponent = gameObject.GetComponent<MeshRenderer>();
     Distance = Vector3.Distance(Player.transform.position, transform.position);
 
 
         if (Distance < availableDistance){
         renderer.enabled = true;    
         }
         if (Distance > availableDistance){
         renderer.enabled = false;
                 }
     }
     
 }

This one works too, the Mesh renderer gets disabled but the object still there like nothing happened, is weird because If I turn the Mesh renderer off in the editor the object its not rendered at all so I dont understand why I cant do the same thing on runtime.
