Passing data from nested SWF to main SWF help?

Hi there.

I have a problem that has stumped me for days.

My main SWF file, “working_login.swf” has a movieclip that loads another SWF file, called “membership.swf”.

http://www.rsupra.com/members/working_login.swf

It loads this SWF file inside of a movie clip which, upon a press of a button, tweens the movie clip containing the “membership.swf” onto the screen.

membership.swf allows you to login using “testing” as the user, and “testing” as the password.

MY PROBLEM:

I have NO idea how to dynamically change the username_txt dynamic text on the main swf.

What I want:

I want it to display “Hello, guest!” when there is noone logged in and no cookie set.

I want the program, upon someone logging in as “testing” to have the dynamic text box display “Hello, testing!” upon a successful login.

Right now, I have absolutely no idea how to go about this. I am using a class to set the dynamic text, but I cannot figure out for the life of me how to set it up to recognize a guest VS someone logged in.

These are the following files that I am using:

www.rsupra.com/flash/membership.fla
www.rsupra.com/flash/working_login.fla
www.rsupra.com/flash/Greeter.as

Any help would be GREATLY appreciated!!!
