I am trying to utilize a logical expression to yield this result:

If the field is blank return a value of no, if there is anything at all in
the field return the value of yes. Basically, I am pulling data out of a
database for a checklist. The user only cares if there is or is not data in
that field. So I am trying to convert the data to a YES and a blank field to
a NO. I would greatly appreciate any assistance. Thanks.
