Adv Guestbook 2.3.1: How to add additional fields/tables

Hello again,

One more question for you...

I would like to add "State", "Country", and "How You Found Me" tables to the database, and add all three of these fields to the form. I want to make State and Country customised selectable drop-down lists to choose from.

What would be required to accomplish this? Can you provide some guidance on what I would need to add and/or modify?

Thanks once again for an excellent app.

Best regards,

Chris Weil
