I looked through the forum  but didn't see this covered.  Trying to play the interactive videos from SzechVR site through the HereSphere but cannot figure how to load the script.  Site has the option to download the script but clicking on it in HereSphere doesn't seem to do anything.  

HereSphere shows the device connected successfully but show "No Scripts Found".  What am I missing?

Are you referring to CzechVR? If you go to czechvrnetwork (dot) com, and then press the web API button, which looks like a play button on 4 tiles, to the left of the url input box, it'll load the web view. You can then go to the interactive videos list at the top, and then the script should automatically play.
