This form asks users if they are ready to select a date and time to book. If they select yes, they can see calendly  on the form and go through the  booking process on calendly to select their date and time. Then, they’ll be taken to the donation. If they select no, it asks them to please explain. 

Note: Calendly and this give lively are separate, so you will have to make a note of those who book and donate around the same time. We could also ask them to make a note of the date & time they booked for on calendly on this donation form if you’d prefer, but it might be a little awkward for users.
