I want to show a message if a number field is blank. 0 is a valid, non-blank entry. I’m using the formula
IF({Number}=BLANK(),"Blank","Not Blank")
where {Number} is an integer. What I’m seeing is that blank values and 0 values are treated the same in this formula. That is, the formula field shows “Blank” for both empty values and 0 values. I would expect this to show “Not Blank” for 0 values.
Conditional formatting will highlight only the empty values, which is what I would expect. So the concept exists.
Is there something missing or is this a bug? Any workarounds?
