Referencing nested clips in an attachMovie clip from it's linked class

Hi!

I’m having a problem referencing nested MovieClips and TextFields that lie in a _root.attachMovie MovieClip that is linked to a custom Class.

I’m trying to reference the nested MC’s and TF’s from that Class (i.e. this.someMovieClip), but it says that there is no Property with the name ‘someMovieClip’.

When referencing actual properties of this, i.e. the ._x or ._y or something, it works fine.

Any ideas?

Thanks.
