I have a sheet with Start Date (date properties), which I have converted to Current Year (text/number properties) in a separate column and then another column called Fully Vaccinated? with dropdown single select properties. In the sheet summary, I have the following formula:
=COUNTIFS([Fully Vaccinated?]:[Fully Vaccinated?], "Yes", [Current Year]:[Current Year], "2022")
This formula returned values when initially created a week ago and when accessing yesterday, I'm receiving #INVALID DATA TYPE error message.
I would appreciate any advice or guidance on what I'm missing.
Thanks,
Sherry
