I am using Access 2003 on a PC running under XP Professional. I have a table called Contacts with a Field named PRN where each contact is allocated a unique 10-character personal reference number comprising 5 capital letters plus 5 digits. I want to use this field as a database on a website as an entry portal to a restricted part of the site. There are about 1500 records in this field. What is the best way to create a suitable database for uploading to my website, please?
