Dynamic Text Flash Pro

Hi, so i'm new to Flash but I am slowly learning. The thing I need to do my not be possible but if it is I would love to know how.

So... I'm creating a quiz on Flash, and on my question screen, I have an avatar that I want animated but I cant have it animated because I  have 12 frames with all y different questions on. It skips to the next scene, when the submit button is hit.

Now, my question and answers are pulled from an XML file, the answers are displayed an Radio buttons and the question in a dymanic text box. Im thinking the only way I can have my avatar animated is to have my question change in the Dymanic text box when the submit button is clicked and have one long key frame (say 35 frames long) rather than having 12 key frames all in a row.

So the question is, can anyone tell me how (if its possible) to get the questions and answer of my dymanic text to change when the submit button is clicked. Without changing key frames?
