Use EXPRESSION BUILDER to REQUIRE selection from drop down list?

Do I need to use the EXPRESSION BUILDER to REQUIRE a user to select one of
the options listed in the drop down of a FORM? Meaning, the user CANNOT move
to the next field until a selection is made from the drop down list from the
REQUIRED field (it CANNOT be left empty).

If so, what is the EXPRESSION I use...exactly, please.

I would forget about requiring a selection "before they leave the field".
Making it required at the table level will do the job. How many error messages
will a person have to see before they "get it"? Not too many in my opinion.
