for some reason it’s not using “using UnityEngine.Advertisements;” and I’m not sure why.

```csharp
FileNotFoundException: Could not load file or assembly 'UnityEngine.Advertisements, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

Which Unity version and have you switched platform to Android/iOS? Also please check the “Ads doesn’t initialize at all” section of [Issues with Ads from Services window? Missing assemblies? - look here](https://discussions.unity.com/t/676820) which has some troubleshooting steps

```csharp
using System.Collections;
using System.Collections.Generic;
using UnityEngine.Advertisements;
using UnityEngine;

public class PlayAd : MonoBehaviour {

    public SuperGold rewardgold;

    public void ShowAd(){
        //if (Advertisement.IsReady ()) {
        var options = new ShowOptions(){resultCallback = HandleAdResult};
        Advertisement.Show ("rewardedVideo", options);
        //}
    }

    private void HandleAdResult(ShowResult result)
    {
        switch (result) {
        case ShowResult.Finished:
            rewardgold.supergold += 2;
            Debug.Log ("Player gains gold");
            break;

        case ShowResult.Skipped:
            //rewardgold.supergold += 2;
            Debug.Log("Player skipped ad");
            break;

        case ShowResult.Failed:
            //rewardgold.supergold += 2;
            Debug.Log ("Player failed to launch the ad,");
            break;
        }
    }
}

```

it says the ads Failed.
