Thank you for the helpful information!
Regarding “For a repeater field the entry for “field” is the number of rows in the repeater.”
1. Since a field group, and hence a repeater field, may be used for various posts with different data in each post, is the number the total of all posts or the total applied to a single post?
2. What is the benefit of storing a count in the database, as opposed to using a counting loop?
Thanks!
