Hey @Bryan_Wang, welcome to the Community!
X days ago is actually a negative number, so
-154. So your formula should read
Style = Pilsner
AND [# of Days] <= -120
But generally, are you creating multiple rules for different types of beer that have different shelf life? A much easier approach would be this:
Add a column
Shelf Life on your Styles table. Fill out shelf lives for each style — e.g. 150 for Witbier, 120 for Pilsner etc.
Create a single conditional format that will read:
thisRow.[# of Days].AbsoluteValue() >= thisRow.Style.[Shelf Life]
i.e. dynamically compare the number of days to the shelf life of current row’s selected style.
