Unity ads troubles

nothing in unity ads is workingusing UnityEngine.Adcertisments;doesn’t work at all. Everything is setup right but it doesn’t work. does anyone know what might be wrong( i am following the unity live training video).

Please provide some more information, e.g. any error message you get

First of all, the namespace is “using UnityEngine.Advertisements;” (not “UnityEngine.Adcertisments”).

For more information, see http://docs.unity3d.com/Manual/UnityAdsHowTo.html and http://docs.unity3d.com/ScriptReference/Advertisements.Advertisement.Show.html for information on how to enable ads and some sample code.

Sorry about the typo. I know it’s not advertisements. I watched the live training tutorial , and am trying to follow it. I am not getting any errors but mono develop is not detecting the unity plugin so it won’t compile. I’m sorry for the lack of information I had to rush.
