That may be so, but I haven't seen any such classes available at my college,
and even if there were, I don't have the time to take one now.

There may have been an error in it - but if you visit a few sites regarding
form validation with PHP and JS they show the same essential layout - in
fact, what I had included was a copy & paste from a tutorial - only changing
the name of the form element itself.

You are just being rude here.

Please see the following sites:
http://www.phpdebutant.com/articles/PHP-form-validation.phphttp://www.php-mysql-tutorial.com/form-validation-with-php.phphttp://www.onlamp.com/pub/a/php/2004/04/22/php_css_forms.htmlThese
are all slightly different approaches, but they all refer to the use of both
PHP and js being used together to validate forms.I was looking for advice
for what approach has proven to work best when much of the data in the
initial form is php-generated (such as populating the list boxes).

Again - very rude. I never said that PHP had anything to do with JS or
vice-versa - I simply wanted to
know the best way to use both together to validate a form.

correct - because js is client-side, but I noted that the onsubmit event
handler didn't find the js function. That is why I even posted my question
in the first place. Our site has a header automatically prepended,
therefore, it's very likely didn't have the js in the correct spot so that
it can be called from the very top of the page (within the initial head
tags) - perhaps as an external js file.

See the above-referenced sites.

It surprises me that some of the people in newsgroups are so rude to those
of us who are simply asking questions because we don't understand or would
like further clarification on how to approach something. If we were all php
or js gurus, we wouldn't be posting questions here. Perhaps I don't
understand the purpose of a newsgroup - I thought it was to share
information, not belittle people.
