Help with a login kind of thing

Hi, i am still new to flash 8, so bee kind…lol

Anyway, i have a movie that i want to put a login area in, the viewer would enter the password and a new window will open that will display the photo proofs for that person. I don’t need a user name, i think i can just use a password that i will be providing. Now i want the password to be stored on a XML file. So i want the movie to look at the XML, see if it exists, then open a pop up with a photo gallery with the proofs for that person from a link that was in the XML file. This needs to be all done externally in the XML, the SWF will not be changed. This way my wife can add new item to the XML and not have to mess up the FLA, she does not even know what flash is…lol

Thanx for your help, in advance!
