HELP - Loading text/ images from external source

I have a client who wants me to create a page with an effect similar to this one:

http://www.paritech.com.au/default-au.htm

I followed the tutorial in Flash MX titled “Loading Text from External Sources” http://www.kirupa.com/developer/mx/multiple_dynamictext.htm

But it didn’t work for me! I’m using Flash 8 Professional.

Can someone give me tips/ put me on the right track to getting something going? I need to submit a proposal on Friday, and really having difficulty working out how to create this. Thank you!
