Advanced Preloader

Hi everyone. I have a Flash file for an advanced preloader that fills up a circle with an image as the file loads. The problem is that the readout on screen is the percentage loaded. I am trying to get it to read kilobytes loaded over the total number of kilobytes, with the image synchronized with the amount loaded. If anyone is willing to help me out on this one I would really appreciate it. I can actually send you the .fla file via e-mail so that you can see what I have. Thanks so much for your help.
