OK, just to ensure we're not talking at cross purposes...
i have created a database with 3 tables, as laid out in the attached file, which you need to unzip
using phpmyadmin, add the tables and query them as follows...
SELECT membername, naicsdescription FROM member JOIN membernaics ON member.memberid = membernaics.memberid JOIN naics ON membernaics.naicsid = naics.naicsid
or for all of the fields...
SELECT * FROM member JOIN membernaics ON member.memberid = membernaics.memberid JOIN naics ON membernaics.naicsid = naics.naicsid
you result set should look like this
