Change image number area: XML/Flash Photo Gallery

I’m following the tutorial for the Photo Gallery using Flash and XML, but I’m wondering how I can customise the number area.

I’d like it to be set out like this:

I prefer the layout with the current image number on top of the total image number (rather than the 2 / 4 format).
How can I customise the ActionScript code so that it works in this format (eg: this is set up using two dynamic text boxes- one for each number)

I’ve been following the tutorial but I’m not sure how to implement this change.

Any help would be greatly appreciated!! (-:
