Thanks for the fast reply. After posting I found an earlier post you had made for a similar issue. Reading that and this one helps me to not just get it done, but also to fully understand what the formulas are doing.

I have the following: Signal 1 Signal 2 Condition A - When Signal 1 > 3500 Condition B - Periodic condition for months I am looking for the average of signal 2 during all capsules from Condition A within a month (created by Condition B). I am looking for a single average number, not the averages of each individual capsule. This seems like it should be simple. Any thoughts?
