How To: Make a dynamic calculator for your news site (using AJAX!)

Have a look at this AJAX tutorial, posted last Sunday by Harry Maugans on his blog. He offers directions, step by step, how to create a simple, dynamic calculator -- and in the process, gives a good explanation on how (and when) to use AJAX (asynchronous JavaScript And XML).
If you have the ability to upload new multimedia files or code to your newsroom website, I'd recommend using this tutorial as a way to get started. You could potentially use this tool to create property tax calculators, income calculators, real estate calculators...useful interactive journalism for your news company's site.
