Hi Adriano,
So, all the thing that are not working in the video, are working on your end together with Toolset bootstrap theme?
I just updated the Scarcity Samurai plugin and WordPress both the most recent version, also it's the only plugin on this install. When I use Twenty Twelve everything works, but on the moment I switch to Toolset Bootstrap theme everything is not working anymore, like in the video.
Do you want me to test it on an other clean install?
I expected us both to have the problem, or both to have it working, but that not the case right now 
. Please let me know what to do next.
Kind regards,
Willem
