typewriter style text

[splendid]

Hi,
Hoping someone here can help me, I'm sure I'm being really stupid or missing something, but im having difficulties creating a very simple button. I have a button that when rolled over makes the curser change...no problem (uses this script:
on (RollOver) {
_root.Cursor.gotoAndPlay(2)
}
)

What I want is to have an mc play at the same time. This mc writes text out, it is very simple, I have the text broken apart, then for each frame a new letter is added until the whole word is there. I have a stop() message at the 1st and last frame. I added the same script as above to the button to make the mc gotoAndPlay frame 2 as well as the cursor. Like this:
on (RollOver) {
_root.Cursor.gotoAndPlay(2);
_root.Text.gotoAndPlay(2);
}

The idea is that when you roll over the button, text comes up at the bottom of the screen.
However, it doesn't work. Ive tried everything I can think of and no matter what, nothing comes up when i roll over.

Im sure ive just missed something real simple.
Thanks a lot for your time and help
Cheers
