just remember, all the cf code executes first, <em>before the page
containing the javascript is sent to the browser</em>

yup   ;o)

yup, possible, and highly recommended to use both -- just not necessarily
on the same page

you could make your cf action page the same page as the form page (this is
a common cf coding strategy and i think we talked about that recently here,
if not here then over on the other evolt list, "thesite")

in that case i guess you *could* code the cf validation to be located near
the actual form fields, but i wouldn't -- too hokey, i like my code
absolutely clear as to intent, which means i don't often code the form page
*as* the action page

also, as aaron suggested, use onSubmit instead of onBlur

onBlur is so annoying that it can drive people away from your site

you <strong>must</strong> do server-side validation, but if you don't also
do client-side validation, you are shooting yourself in the foot

for one thing, it is way more efficient for the site visitor

also, coming back from the server with an error message means you have to
repopulate the form fields, otherwise the site visitor has to retype even
the valid fields

which is so annoying that it can drive people away from your site

i am *really* late for the office today.....
