Two drop down box

[NZ_Kiwis]

I have two drop down boxes. When I select a option from the first one I want it to change what's in the second one... how can I do this?

I was looking for a solution to this yesterday, when I discovered a way to do it using AJAX...

I found a really easy to understand and use tutorial here
http://www.fornewbie.com/article/php/create_ajax_dynamic_drop_down_list_using_php-xajax.html

This script is easy to customise and you can have 2 or more select drop down boxes.

XAJAX = PHP + Ajax library
... is very interesting!

Xajax, home+download: http://www.xajaxproject.org/

Introducing xajax 0.2.4
Ajax-enable your PHP application with a simple toolkit that gets the job done fast.
Runs on any PHP 4.3.x/PHP 5.x and Apache/IIS platform.

What is xajax?
xajax is an open source PHP class library
that allows you to easily create powerful, web-based, Ajax applications
using HTML, CSS, JavaScript, and PHP.

Applications developed with xajax
can asynchronously call server-side PHP functions
and update content without reloading the page.

==========================

We also have this similar and very good Ajax Framework Library (not PHP):

PrototypeJS, home+download: http://www.prototypejs.org/

Prototype is a JavaScript Framework
that aims to ease development of dynamic web applications.

Featuring a unique, easy-to-use toolkit for class-driven development and the nicest Ajax library around, Prototype is quickly becoming the codebase of choice for web application developers everywhere.

Introduction to Ajax
Prototype framework enables you to deal with Ajax calls
in a very easy and fun way that is also safe (cross-browser).
Besides simple requests,
this module also deals in a smart way
with JavaScript code returned from a server
and provides helper classes for polling.
