First of all, just wanted to say the custom fields are brilliant. They were easy to set up and seem to work great for adding different fees to a basic registration. I did have two problems.
1. I chose radio fields because I have three options and want someone to choose only one. However, they can go in and check two or three options. In other words, when you click one option and then change your mind and choose a different option, the first one stays checked. You do not seem to be unable to uncheck it.
2.When you are setting up a new registration in Event Management, is there a way to automatically make the custom fields default to No, Used for this Event. Right now they default to Yes and you have to remember to check No. In my case, the majority of classes do not use the custom fields.
