Application Design: Dynamically change state and city drop-down boxes with DHTML

i've previously joined builder.com, i'm on the mailing list. when i try to login to get the example i'm told an account does not exist for my e-mail address. when i try to create an account i'm told an account with that e-mail address allready exists. so which is it?

...NFL does it, CBS does it, you can do it. Take a look at http://www.knowmysize.com/blog/index.cfm?mode=entry&entry=64A95139-7E9C-B5BD-B17215A01EF8A6DD for the JavaScript server communication method of populating data. Simply put, any element on your page can do a dynamic (runtime) look up and retrieve data from a CFM page, JSP page, or other and update fields on your current page without refreshing.

Thanks for this great article. I am trying to implement the technique described, but it would be a big help to know what the database being used for the example app looks like. Is the state repeated in column 1 as many times as there are cities in column 2? Or is it organized in a different way?

did this code work for anyone using coldfusion? If yes i appreciate your help in running this successfully...Also i'm looking for the 4 combo box combination dynamically from the database like the exaple is showing....
