Dynamic box resizing

Question

I was using this FLA as an example to do my own progress bar
app.
http://www.flashkit.com/downloads/movies/zip/8327/Simple%20Progress%20Bar%20Preloader%20-- %20Dynamic.zip
I created a new box -> movie object and naming the
instance "bar"... the "setProperty("bar", _xscale, iBytes);"
This works for a one time deal, but when I try to loop as the
FLA file does, nothing happens. Yet when I do the same thing with
the movie clip in the FLA file, it works fine. What do I need to do
to my movie clip object to make this work for me?

Answer 1

Figure I would post this if anyone else was interested.
I think I answered my own question, at least in this case, where I am using the UI text Scroll Component
I make the text box first and drag the bottom center resize handle to make it the size I want.
Next, I add the UI text Scroll Component to it at the right size
Finally I paste the text last and it works fine.
For this case it works....but it would be nice, like in other programs, where you can re-size a box without effecting text size
