Gravity forms and Appointments+

Hello I require a field to be brought over two appointments field. For example enter a bunch of questions and gravity forms and giving me a code this code is transferred to the field with an appointment book. I've been in contact with the developer is a gravity forms and they say it is possible to get information out of their fields we just need to know where to put it in appointments plus.

How can the appointments+ plugin accept information? When they land on the page to make the appointment, how can you add a hidden value to the 'appointment request'? We don't have any experience with that plugin, but we can help you get information out of the Gravity Forms entry, if you can tell us what you need to do with it.
