Trying to get an object to disappear

I am making my first game a roller ball game. I am trying to open a new area of a level when I collect a pick up. I have the pickup created and it will dissappear when I roll over it however the statimeshactor will not disappear. Below are pictures of my blueprints. I am not sure where I am going wrong. Do I have to have a setting for Cube11 which allows for it to be destroyed? I checked and could not find anything that might relate to this but maybe I am missing something. Thanks for the help
