AS3 equivalent to attachMovie


I think I’m close to figuring this out – using addChild, but I just can’t lock in. Basically, I’m trying to create a pop-up box using the Timer event, where when someone mouses over a button a box pops up similar to using attachMovie from AS2. And when they mouse away from the button the pop-up box fades away. I’m getting my AS2 way too mixed in w/AS3, and I’m confusing myself on how to make this work as a function. Any suggestions?
