multiple animations using actionscript?

I have this problem where i followed a quick tutorial to create scrolling text which works great. Basically in frame 2 the next letter is printed and in frame 3 i have a got frmae 2 which goes on and on ...

The aim of this was to make an animation of my friend with his jaw moving normal tweening whist in time to the scrolling text. However, i am unable to do this because of the repeating nature 23232323232 etc ...

What is the normal way to get around situations like this? Is it possible to have both these animation working in tandem?

ok i have done it by converting the text box to a movie clip and putting actionscript in the movieclip

sorry for the inconvenience.
