Hi Nimmi,
If you know all your users have JavaScript, for example if you develop a
corporate intranet with Netscape 4+ or MSIE 4+, then there's a trick.
The first HTML page below shows how to use JavaScript to determine
the index and label of a select-one box. The second HTML page below
shows how to automate the trick for all of the select-one boxes.
When you try the pages, be sure you can see the URL in your browser.
You will see the hidden text fields getting filled correctly.
If your users might have older browsers, or might have JavaScript off,
then go with Andy's solution; his is much more robust and flexible.
Cheers,
Joel
