Externally Loaded Dynamic Text Dilemma

I run a website for a gaming group and I am constantly having to update because we gain or lose members daily. My current setup has each members information being loaded into a dynamic text field from a single .txt file.

I would like to be able to update the members section without having to reproduce the swf every time, yet still keep the appearance of each member having their own section of information.

Is there a way to change the variable or instance name of a dynamic text box with a button code? (In a way that I could press the button and the text box would reference a new variable inside of the same external text file.)
Any and all help is appreciated, because I am stumped. Thanks! :smile:
