Hi - I'm ready to code this feature.
Here are the fields:
Choose a class:
How many students are you enrolling: #number
What I need to do it keep a running tally of how many students have signed up for Class A and how many have signed up for Class B. Once a class enrollment has exceeded 100 then I needed to hide the Class A (or ) option and begin displaying the option Class A Waitlist (or Class B Waitlist)
