Script: Scrolling Text

Create a dynamic textfield, click on it, give it a unique name and get the scrollbar from the components menu. Attach the scrollbar untill it fits automatically.
loadVarsText = new loadVars();
loadVarsText.load("text/cancer.txt");
//assign a function which fires when the data is loaded:
loadVarsText.onLoad = function(success) {
    if (success) {
        //Now that we know the data is loaded,
        //set the text content of the Text Field
        //with the instance name "scroller" equal to the
        //contents of the variable
        scroller.html = true;
        scroller.htmlText = this.cancerText;
    } else {
        trace("not loaded, try again!");
    }
}
