Flash newbie needs help

Question

i'm quite a newbie when it comes to flash and need some help
http://www.sas.se/sv/?vst=true
you look to the right you'll see an airplane and i'll say "Billiga avgångar" next too it
under the text you can see text in yellow being scrambled then reappear
i was wondering how you make the text scramble then display the messeage like that?

Answer 1

this is a better way to do it in one textfield.  it's easily amended to display one letter per textfield and add textfields as needed.
(to speed up the display shorten charS even down to a one character string.)
var charS:String = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ 01232456789,./<>?;':\"[]{}\|!@#$%^&*()-_=+";
var charA:Array = charS.split("");
var displayTO:Number
// user defined params:
// character change in ms
var speed:Number = 1;
encodeF(yourstring,yourtextfield);
function encodeF(s:String,tf:TextField){
    tf.text = charA[0];
    displayTO = setTimeout(displayF,speed,s,tf,0,0);
function displayF(s:String,tf:TextField,charNum:Number,index:Number){
    tf.text = tf.text.substr(0,-1)+charA[index];
    if(s.charAt(charNum)==charA[index]){
        tf.text += charA[index];
        charNum++;
        index=0;
        if(charNum<s.length){
            displayTO = setTimeout(displayF,speed,s,tf,charNum,index);
        } else {
            tf.text = tf.text.substr(0,-1);
    } else {
        index++;
        if(index<charA.length){
            displayTO = setTimeout(displayF,speed,s,tf,charNum,index);
        } else {
            charA.push(s.charAt(charNum));
            displayTO = setTimeout(displayF,speed,s,tf,charNum,index);
