and button script

 public void removead()     {          destroy (gameobject.find ("advertistment"));     application.loadlevel ("minigame");//this replay game     } } 

maybe should use script instead of deleting it.

try calling:

gameobject.find ("advertistment").getcomponent<disablead>().removeads(); 

of course add null checking.
