Random text fade in/out

hello,

this may not be an advance actionscript, but i need your help guys…

i found this loading random quotes - http://www.kirupa.com/developer/mx2004/random_quotes.htm,
but changed the code a little bit that it loads randomly without clicking the button:

function newquote(){
    play();
    clearInterval(auto_quote);
};

ranQuote = new LoadVars();
ranQuote.onLoad = function(success) {
 if (success) {
     RanNum = Math.ceil(Math.random()*5);
     ran = this["quote"+RanNum];
     quote_txt.text = ran;
 }
 else {
     quote_txt.text = "The text failed to load due to an error";
 }
}
ranQuote.load("quotes.txt");

stop();

auto_quote = setInterval(newquote, 10000);

my question is:
how to let the text fade in/out when it loads another quote?:pa:

any help will be greatly appreciated! :blush:
