URGENT Help Requested! (Dynamic Text Box)

Okay, here is my situation…

I am setting up a webpage with Flash MX. On the homepage I have a dynamic text box with links to the left (currently the links are just typed words). We want it to setup so that when a user clicks a link (such as "HOME") it will access text from a .txt file and load it into the dynamic text box. We want all of the links ("HOME", "PERSONNEL", "RECRUITS", "CONTACT US") to load their text from a seperate .txt file into that same dynamic text box. I would really appreciate a rather immeadiate response if anybody is able to help us, thank you.
