Hello. I am working on a formula to calculate how often an Account Number (Nominee C#) appears in a column. If it appears more than once, then a box gets checked. I have this part built and working, but now I need to add an additional parameter to only checkmark the box if they have appeared more than once in the last 365 days.
Here's what I currently have without the 365 days parameter: =IF(COUNTIFS([Nominee C#]:[Nominee C#], [Nominee C#]@row) > 1, 1, 0)
Any idea how to add that additional 365 day parameter in?
