Need Help With Unity Ads Results

I Need The Results Of Video ad (skipped,finished or failed)
here Is My Ad Script:

using System;
using UnityEngine;
using UnityEngine.Advertisements;

public class Ads : MonoBehaviour {

	void Start() {
		if (Advertisement.isSupported) {
			Advertisement.Initialize ("66815");

		if (Advertisement.IsReady ()) {
			Advertisement.Show ();


As the link shows, you can put anything into the callback function so that it is called when we have the result of whether the ad Failed, Skipped or Finished:

string adResult;
float start = Time.time;
Advertisement.Show(null, new ShowOptions {resultCallback = result => {
		adResult = result.ToString();

		//Do something else once we know what's happened
		//Call some function


		//try again if failed?
		if(adResult == "Failed"){

		//Add some ingame value if advert watched
		if(adResult == "Finished"){
			Debug.Log("Yay, they watched the whole thing!");
			AddIngameMoney(Mathf.FloorToInt(Time.time-start)); //add money based on length of ad?

Maybe that helps?
