FMP3: finding empty records

[MP Frosch, MD, PhD]

I have a database which keeps track of my animal colony.  One of the
files consists of the individual cage names.  This is connected via a
portal to a database of animals in which the current cage location
appears.  In the cage database I perform a calculation to find out how
many animals are in a cage.

Within the case database, I can do a FIND and get cages with any
different number of animals except zero.  Why can't I find my empty
cages?

TIA.
