Extend the interface of an existing site so that customers can register a tag number along with their information. existing programming is not performing correctly and needs to be changed.
1. Customer must be able to register a tag number this tag number will do a lookup in the MySQL database to see if it is already used. If already used then tag cannot be entered (try again) if NOT in use then add the person information and submit.
2. If this person registering a tag information is already in the MySQL database then just add the tag number to thier "account" please look at database ( have account login for cPanel)
3. Code is PHP, Ajax, HTML
4. Site is live
