T-Bone, I understand your question a little better this time. You could solve this problem by creating an AGGREGATE QUERY which will eliminate duplicates based on the fields you select. You could "group by" company name or address, for example.

Or, you could simply add a Yes/No field to your table called IncludeInMailings. If this box is checked, then that person gets mailings. You could uncheck any duplicates for that company - this would allow you to control WHICH contact at the company gets the mailings.

Or... the BEST way to handle the situation would be to have two separate tables: one for companies, and one for people at those companies. Your company table could then have a field for you to select the primary contact. But if you've inherited this database from someone else, this would be hard to retrofit.

Hope this helps.
