=IF(COUNTIF({Client Name (Pruning)}, [Client Name]@row) = 0, "", COUNT(COLLECT({Annabelle Name}, {Client Name (Pruning)}, @cell = [Client Name]@row)))
The above formula works great after receiving help from a member of this community :)
The formula is counting the rows with the criteria; however, there are duplicates counted for various reasons. I'd like to limit the counts of for example "Annabelle" above to one for the same submitted date on the reference sheet. In other words, if there are three rows with the date of 5/09/2025 and "Annabelle" is part of the row, I want to count it only once. Additionally, if there is another distinct date of 5/12/2025, I want that to be counted once. Consequently the four rows of info would add up to TWO.
