Thank you. That works as shown in the video and in the comment above. In the video you point to the field group having underscores instead of dashes. I'm guessing that would come into play if I was doing a loop on a page, so I will keep that in mind. In my test for this case the field group name didn't matter, I guess because it was not referenced.
I noticed that by default Meta Box puts dashes between the words in the field group name.
