Complex button mc

Can anyone help me out with the script for how to nest a button with in a complex “button” mc (like the complex button tutorial here on kirupa). Basically, I want to make a button that will “rewind” with the mouseOut, but with the mouseOver will open to two buttons that each have a loadMovie function. I’d like to use AS3.0, but so far I’ve just found AS2.0. I’m not that picky though.

Thanks in advance!
