ActionScript Positioning

Okay here is what i want to do. I want to have a movie clip that starts in the middle of the stage. This MC will have the navigation inside of it.

Now when you click on, “Work” I want “work_mc” to come in from the right of the screen and i want the navigation mc to shrink down to a smaller size and have the alpha go down to about 75% Inside of work there will be different types “Print” “Web” “Multimedia” and when you click on one of them, “print_mc” comes in from the right and the origional nav shrink even more and the alpha goes to 50% and then the 'Work_mc" shrink to the size that the nav was and its alpha moves to 75%

I have absolutely no idea how to do this :slight_smile:
