Description of my issue:

We have events that offer free registration for members, and paid option for non members. Can you help us hide payment requirements on the second page of the form for those who entered their ID in our "Membership ID" field? There is confusion with the client why they are required to select a payment option when they selected the free ticket. Thanks!
