I'm trying to learn some Ajax and MySQL...

Basically, the code that I have right now is similar to: http://www.w3schools.com/PHP/php_ajax_database.asp

I was wondering how should I modify those codes (both html, javascript and php) to create two drop down lists. The first drop list would be used for choosing the Lastname (eg. Swanson) and the second drop list would be used for choosing the Hometown (eg. Quahog). Then the user would click "Submit" button and the query would return the matching results (eg. all the Swansons living in Quahog).

I'd be very thankful for all the ideas!
