Dynamic Flash self updating form.. Help

Hello to all,

I am trying to build a Flash form that allows a user to select a time slot for an event from a list of about 10 possible times they can attend. I also want to collect there name and email address in order to send a confirmation to there email inbox. When they hit submit, i want the form to update in real time, displaying the time slot they selected as unavailable so that there are no overlaps with the times selected by users.

Has anyone ever done anything like this in Flash? Is there any tutorials on the web that you can refer me to?

Im pretty familiar with Flash Forms, and integrating them with PHP. Its the real time updating that i am needing the most insight to.

Thanks in advance
