or if you want the SQL statement it would be
SELECT (all the fields you want to show up...i.e. last name, first name, address etc)
FROM (name of table)
WHERE LastName="A"
ORDER BY (which field asc or dec)
jus simply use the wizard for the queries and drag in the appropriate fields....in the criteria section of the family name field put in 'a' and RUN the thing...u should end up wit the desired results
