i used to have a news page, on a band site i run. pressing the news button would load the news.txt incude, and make the news window (a movie clip, called 'news') visible. to do that, i used this code on the news button
on (release) {
loadVariables ("http://www.domain.com/flash/news.txt", "_root.news.textMovie");
setProperty (news, _visible, true);
}
i hope that's of some help to you...
