Andy, I suggest that you buy (or borrow from a library) a book on relational data base design. To give you the simple answer to your question: have one table for the broker's name and identification and a separate table for their addresses. It's called a many-to-one structure and is created by normalizing the data. Rich Dr. Richard B. Shepard, President Applied Ecosystem Services, Inc.
