I was hoping to be able to find the answer elsewhere but have had no luck. I was able to build the following formula from other answers but stuck on the last part of the criteria (Warning Items) being in a multi-select drop down. So the formula works but is incorrect in that it does not count cells where there is more than one option selected.
=COUNTIFS({HSE Observations Range 3 Audit Date}, <=StartDate@row, {HSE Observations Range 3 Audit Date End}, >=EndDate@row, {HSE Observations Range 2 Warning Items}, [Observation Item]@row)
Could someone help with the solution? Is this even possible? Any help would be appreciated.
