Having Issues with Simple Buttons

I’m working on a game with a lot of potential but I am not a c# developer and I am banging my head trying to do easy things in Unity.

My script is simply not working. It’s not the C# part I am having issues with. It’s linking it to the button.

With that said I am looking to hire a few good unity developers.

using UnityEngine;
using System.Collections;



public class UrlOpener : MonoBehaviour
{

  public string url;

  public void Start()
  {
     //Application.OpenURL("http://google.com");
      Debug.Log("is this Start?");
  }


  public void Open()
  {
      Application.OpenURL(url);
      Debug.Log("is this working?");
  }
}
