Displaying Hover Captions

I am trying to make the box that pops up when I hover over the button fade in when you hover over, but everytime I put a stop on the movie clip it won’t work. how do I fix that. Also I would like to know how to make the movie clip two parts. check this link out. it is at the bottom of the page, the arrow stays tight with the mouse but the box above it is on a delay, I was wondering how to do that. thank you very much
