Results not appearing when hovering

For my theme’s demo, the results of the ratings appear when you hover over the stars, but I can’t get them to come up on my own site: http://www.thingsworthdescribing.com/

I’ve been searching for a while now, and haven’t been able to find any “hover” options in the settings – any help would be much appreciated!
