[FMX]:attachMovie: simple question

hullo everyone,
i appologise if my post is confusing tonight… i’m all tired out… and this AS has been eluding me all day.

Can i get the _y position of a movie instance generated by the AttachMovie method? i’m trying to do something like this.

_root . mc full of attachedMovie instances . one of those clips . _y

the path i’m really using looks like:
_root . text . infoblock4 . _y

if anyone could give me an example of the proper way to do this i’d be most thankfull.
