Need help with simple button problem

Uber was more than generous enough to help me with a ton of things concerning my portfolio and animating it in Flash. However, I need more help than just him apparently. He’s been busy with his life and I am to a point of no return. I was hoping someone would be willing to help me out by explaining to me how I make a button load text into a text window. I have a very nice pre-made text window, but I am not sure how to have it change text when a button is clicked. Aside from that, I think I am done. I greatly appreciate any help anyone can give me. Thanks in advance!
