MX Scrollbar not working with dynamic text

I am really having trouble getting my dynamic text field’s scrollbar to scroll properly with dynamic text.

I have every method i can think of… from setting the text using actionscript (below) through clip events, frame actions, etc. no matter how i set it, the text is loaded correctly… but the scrollbar will not adjust.

I have also tried the flash 5 method of just setting the variable… nothing works!! have read every example and reference on macromedia and tried all of them… please help!
