How can I limit number of hits per multiple choice option

I have set up a sign up form for students to choose one club from a multiple choice list. Once a club has reached 15 spots I do not want the kids to be able to choose, as the club will be considered full. How do I add these parameters?

We have a few different widgets that will allow you to set up options and limit the quantity available for those options.  For your purposes, either the appointment slots widget or quantity gift registry widget would probably work best:
