Same css, different loaded texts and flags

Hello!!! I need your help!!!
I’m starting in Actionscript 2.0 with Flash MX 2004.
I’m making my web site in 3 languages (Spanish, Italian and English).
I don’t want to make 3 differents sites, i use this example:
" http://www.kirupa.com/developer/mx2004/cssfile.htm "
But I would like to know:
How can I load 3 text with the same CSS?
I would like to load the text clicking on the differents flags (movieclips) in a “_parent” movie flash. How can be maintained the option selected?

Thank you very much for spend your time reading this!!!

And excuse my English.
