Directing mc in mc (mx 2004)

Hi, i installed mx 2004. I am currently working on a site and i need to target a mc which is another.
For example if A1 is in A, in normal Flash MX i should’ve done this:

_root.A.A1.gotoAndPlay()

but it didnt work for 2004. i mean it targeted the A, but couldnt see the A1. Is it different in 2004?

Thanks
