Crystal Section Suppression

I have a Details section with one text field and three user-defined fields. I need to suppress the section if any of the fields are blank. To make it easier, I just selected one field. I checked the "Suppress Blank Section" and entered the formula {Field Name}=FALSE.

I have tried other fields in the same section with formulae, but nothing is getting suppressed.

What am I doing wrong?

Thanks in advance for the help.
