Trust your users, do ya? <wry grin> If you don't want to handle validation
on the server side using PHP, you should probably look at a JavaScript
solution that checks to see if the number is between a given range after
some event (like the form element losing the focus) and popping up a dialog
box if it's not valid. Try internet.com's Javascript area or another JS
site to find a code snippet that does what you want.
