The Minimum Talks Required setting lets you require attendees to choose at least a set number of talks before they can complete checkout.
Use it when attendees should build their own schedule, but you want to make sure they select one or more talks.
Go to Event Setup > Registration & Checkout. In Can Attendees Build Their Own Schedule?, choose Yes, then enter a number in Minimum Talks Required.
If the field is blank, attendees can choose as few or as many talks as they like. If you enter a number, attendees must select at least that many talks before continuing.
When a minimum is set, attendees cannot skip the talk-selection step during checkout.
This setting is different from Auto Register To All Talks?. Minimum talk selection asks attendees to choose talks themselves; auto-register adds talks for them automatically.
