Animate 360 Beta Scenes

Not sure if its a Beta thing but im trying to load "Scene 2" by clicking onto a button from "Scene 1" but when testing nothing happens.  Is there a specific way I should be doing the code (code snippet doesn't work either).  

Is there a way to take a produced 360 html file (File B.html)  and load it into my other 360 html file (File A.html) using an eventListenter "MOUSE_DOWN" load..............("File B.html).  I hope this makes sense and Im sorry if it doesn't I haven't coded in a very long time so Im just trying to figure this out for a demo im working on. Thanks for any help!
