PLEAASEE I NEED HELP!!! How to turn Mesh Renderer of cubes on and off by pushing buttons?

Question

Hi everyone,

Please help me with this. I want to enable and unenable the meshrender of the cubes by pushing "e" and "u" buttons, but it didnt work. Everytime I pushed those button nothing happens. I don't know how to fix it (T..T)

The code is as below. What I did was that I extracted positions and colors of the cubes from a csv file. (I cant upload the csv file, I upload the txt file instead in case that if you need the file to run you can change it back to csv file).

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Transparent : MonoBehaviour
 {
     public TextAsset CSV;
     public GameObject Cube;
     public static bool click = true;
     // Start is called before the first frame update
     void Start()
     {
         string[] myCSV = CSV.text.Split('\n');
         for (int i = 0; i < myCSV.Length; i++)
         {
             // Positions of the Cubes
             GameObject myCube = GameObject.Instantiate(Cube);
             string[] values1 = myCSV[i].Split(',');
             float x = float.Parse(values1[0]); // column 1 of the csvfile
             float y = float.Parse(values1[1]); // column 2 of the csvfile
             float z = float.Parse(values1[2]); // column 3 of the csvfile 
             myCube.transform.position = new Vector3(x, y, z);
 
             // Colors of the Cubes
             float r = float.Parse(values1[3]); // column 4 of the csvfile
             float g = float.Parse(values1[4]); // column 5 of the csvfile
             float b = float.Parse(values1[5]); // column 6 of the csvfile
             Renderer myrend = myCube.GetComponent<Renderer>();
             myrend.material.color = new Color32((byte)r, (byte)g, (byte)b, 255);
 
             //MeshRenderer of the Cubes
             MeshRenderer cubeMeshRenderer = myCube.GetComponent<MeshRenderer>();
             cubeMeshRenderer.enabled = click;
 
         }
 
 
     }
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKeyDown("e"))
         {
             click = true;
         }
         else if (Input.GetKeyDown("u"))
         {
             click = false;
         }
     }
 }

          }
