Text in dynamic text are gone?!

i have a dynamic text box which loads some text from server script. It works when tested in author env or all by this individual swf. But when combined in a big project and loaded as a movie, the text from server doesnot show.

i am pretty sure the text info already reach to the browser (i can watch the traffic of browser). So, anyone, any clue are so appreciated.

i am new to flash. from a programmer view, flash can compare java applet. anyone agree? Thanks
