Hooray! Glad you figured it out.
Have you been before? If not, here’s my hint. They videotape some of the sessions, and they show you on the course list after you arrive what is being taped. For stuff that I really think is going to be good and I want to remember it later, I’ll buy the video. Sometimes, there are two classes at the same time that I want both classes, so I go to the one that’s not being videoed and I purchase the video.
