Enhancing a web database search table

I have created a search table with many fields (Correspondents List). link below
http://www.else.co.uk/chartererscorres/charterer_ajax.php

I have allowed users to search for everything on the table but when they click on a field they will see a details correspondent (pop window) with a list of names, city etc.

I need a query built into the database which creates a list of names who are apart of the company, currently I only have one name listed, however there are times where one company has 3 contact names associated with the company name, I would like all the names associated.

Please contact me if you have ideas on how this can be developed.

Kind regards,

Mits
