A question from a newbie

Hi, im still a newbie in this flash thingy and i really need your help guys :P.
I’ve made an interface in flash and i also have made the buttons as well as putting some texts on top of the buttons. So, when i rollover on the button, the button will move down a bit.

Now what i really want to do with it is to make the texts to move along the button as it moves down.
Plz help me…
