I need to eliminate duplicate addresses in a mailing
list. I only want to
send to one letter to "family" at each address. I have
assigned the last
name column to a range called "Lname" and the full
address including
city/st/zip to a range called "Addr". What would be the
best formula to
review 60000+ records for duplicate last names at the
same address?
