We have a site that has several Membership options for classes. Example:
1. Select the number of Adults for the plan at $10 each, a custom fee field.
2. Add an Extra Class for the week, another custom fee field for the week to the Adult plan at $8 each.
However, our problem is figuring out how to keep the Extra Class field to either not show or not work unless a person first selects the Adult plan choice. Currently I can skip the first step and pay the discounted price for adding and Extra Class.
