If you are sending people on a missions trip or to camp and want to allow people to donate to the trip, you can set up a fund in Giving, link to that fund from the Registrations event, and adjust the scholarship fund as donations come in.
If someone wants to apply the donations to a specific person, the donation won't be tax deductible. The Event Manager would need to apply the donation directly to the attendee's registration.
1. Create a Fund
From Giving, create a fund to contain all the donations for the missions trip.
3. Adjust Scholarship Amount
As donations come in, you can make changes to the scholarship amount to be able to apply scholarships to attendees.
View the fund from Giving, and create a scholarship with that amount in it.
As more donations come in, change the amount to the total reflected in the fund.
