Form field validation and ASP

Hello

I have a simple Flash contact form with name,email, message, etc fields and would like ASP - not Flash - to validate the fields. So if a site visitor completes the form and presses ‘submit’ while having omitted the @ sign, for example, from his email address, then ASP would tell Flash to display something like ‘Please complete the email address field’.

I have some ASP (VB Script) which does this, but how do I pass it to Flash, and how would I get Flash to display it in a simple dynamic text box next to the form? And what happens if more than one field has been incorrectly completed?

Many thanks for any help.
