Thanks, Julian. I have a follow-up question regarding your solution. You
include an onchange Javascript handler where you submit the form, at least,
I assume that's what submit() does. How do I submit the form, keep it on
the same page, preserve the values that were already entered, and not prompt
validation? Is it as simple as "this.form.submit();"?
Thanks, - Dave
