actionscripting - age check tool

I have a flash movie that requires a user to enter their date of birth via a drop down menu - once the user has entered their data of birth and are verified to be 18 or over - the flash movie continues and re-directs the user to a web address. This actionscript has already been written and is working. I have an html version of the flash movie that uses a php script to set a session variable that ensures users cannot access pages directly without first confirming their age. I basically need to implement the same in actionscript. Can send further details if requested. Looking for a very quick delivery on this (wednesday 14th feb preferably).
