Hello, my organization collects donated items to sell at market.

I have a base with two tabs: A calendar view of events (Collections, Donation Sorting, Selling) and a second tab with a list of donors and volunteers (who are often one and the same).

Under the second tab, I have a view form for donors to complete. I would like them to be able to schedule (i.e.select) only future collection dates (we collect every Sunday every week).

I need some help… how can I best do this?
