RE: [PHP-DB] Getting the value of an auto-increment

Wow, thanks for such a great resposne! Sorry I should have clarified that I am using MySQL. The mysql_insert_id() suggestion worked perfectly and reduces the amount of code I'm running from about 12 down to 1! Thanks for all the help, it's greatly appreciated.
