Actually I saw that extra div and had to delete it from my page because it was messing things up. I guess I wasn't totally sure if it was a problem specific to my site because of the special formatting I'm doing. Regardless, it now looks good and the button is appearing.

P.S. in the contrib I downloaded only yesterday or the day before there were no button instructions included....only a reference to "Alternately, you may use the button provided."
