Form validation

I have a simple flash form, which has some required fields, ie. name, addy, etc.

What I want to do, is validate that the fields have been filled before they can hit the “next” button.

I’ve searched the forum, but found nothing, so I appologize if this has been asked before.

As you know, my AS understanding is intermediate at best, but I don’t think this is beyond my capabilities.

thanks in advance, this will score big with the PM…
