The arrow shows the button "GET TICKETS" if you press that button you will be brought to the "Calendar Options"
Also you can Click the "REGISTER" button and be brought to the same place to pick your calendar options and follow the directions from there.
The "Donate Now" button will bring you to a donation page only. To get the calendar options, please follow the "Get Tickets" or "Register" buttons.
(We had to retrofit that site because it normally is not used for purchasing such things as calendars.)
