You have to find and then sort to get to a record matching this criteria. Perhaps that added sort is what has you stymied.
Are you able to find the records for all meetings lead by "Uriel Kovats"?
Can you find those records but also for meeting dates earlier (less than) than today?
If you can do that and then sort the found records by meeting date in descending order, the first record is the past meeting closest to today's date.
The way you described it is the way I thought about doing it. However, this part of the tutorial was about using the Find Mode. I thought that I was supposed to use specific Operator in the Find Criteria. Thing is, I couldn't find that operator.
Anyway, no more fretting the small stuff. I'll do as you suggested and continue on 'The Path'.
