I noticed that the DTRegister demo has an optional field "Need Lunch" that can dynamically reduce the register amount by $5 if "no" is selected. Is this the old "Additional Amount" field that was removed or is this a feature that's available through custom fields? If so, can this be done? I need to create a optional field for "Single Occupancy
The option of custom fields adding or reducing the registration cost is in the new 2.1.4. This will be released this weekend. Be watching for an email notifying you of the release being ready. When it is, you can login to your account on this site, go to "My Orders" and download it.
