Please see 2 screen grabs below. The Excel table I am using currently has 10 rows. However, over time it might grow as more records are added.
The Flow works great in that it emails me a warning when an event has expired - but it's trying to make it send some type of 'OK' message when the events are all in date. Currently no message is sent if all dates are ok. When I've tried adding to the 'IF No' option, I get 10 messages.
