Simple newbie button question!

I have a button, and when on mouse over, it goes to a frame inside my button and sorta does an animation. But when over the button i also want a description of the page it’s leading to. I dont want this to be included in the button, but just a seperate frame somewhere.

Can i have the button lead to one frame in the timeline inside the button, but also a frame in the main timeline? Is this possible, has anyone got any examples?
