Dynamic Calendar - xml - loadmovie

Hi

I am trying to create a dynamic calendar where a user clicks on a
date, a text field is created/populated on one part of the main flash
movie & a movie loaded in another part. I have seen examples at =

= > http://www.webagent007.com which uses an xml file,

= > http://rahel.burbacher.org which uses a MySQL database & PHP.

I have searched high & low for info on how to do this. Any clues or
pointers on how to achieve this ?? Links to tutorials are always
appreciated.

Thanks in advance
