Variable in Dynamic text field

Question

Hi,
I'm trying to build a custom keyboard into flash to display text in the interface.  So far all that I have tried failed, can anyone point me toward a simple script or tutorial that would help me out.
Thank you

Answer 1

ok here's a description of the project:
I made a Movie clip containing all the buttons needed to make a QWERTY keyboard, plus some special character.  I would like text to appear in a dynamic field when the user click on the button, so they can write text in the field.
So far, I've tried the following code, but it's not working :
Frame 1 :
stop();
var myText:String;
input_txt.text = output_txt.text;
next_btn.addEventListener(MouseEvent.CLICK, nextClick);
function nextClick(myNextEvent:MouseEvent):void {
    captureText();
    this.nextFrame();
function captureText():void {
    myText = input_txt.text+"q";
Frame 2 :
output_txt.text = myText;
back_btn.addEventListener(MouseEvent.CLICK, backClick);  
function backClick(myBackEvent:MouseEvent):void {
    this.prevFrame();
I'm pretty sure this isn't the most elegant way to do it, I've made it work once in a separate project, but I can't make it work in the new one.
Does this help understand my problem?
