Use preloader for individual frames?

Question

I have followed this video on how to build a preloader and I was able to incorporate it into my own site.  Now, I'm wondering now how to build a preloader for individual frames.  For example, I have a link called "Videos" that, when clicked, jumps to frame 10.  This is where I have all the videos visible in the main content area of my site.  However, I'd like to add a preloader so that as the videos load, visitors can see the progress.  Is there a way I can reuse the preloader.swf file I have already built for individual frames of my main site?
Here is the code for the preloader.swf file which consists of a single dynamic text field located in the center called preloaderTxt:
var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
l.load(new URLRequest("WebsiteTest.swf"));
function loop(e:ProgressEvent):void
    var perc:Number = e.bytesLoaded / e.bytesTotal;
    preloaderTxt.text = Math.ceil(perc*100).toString() + "%";
function done(e:Event):void
    removeChildAt(0);
    preloaderTxt = null;
    addChild(l);

(1)Java class name should begin with a capital letter. See: http://java.sun.com/docs/codeconv/
        JButton save = new JButton("Save");
        JButton save2 = new JButton("Save and add another");
        // ... etc. ...(2)Don't redeclare class members in a method as its local variable. Your class members become eternally null, a hellish null.
how to make them work when clicked on(3)Add action listener to them.
