Can't change text alignment in nested Movieclip

Hello everyone,

I’m using ActionScript 2 and I’d like to change the alignment of the textfield. This is possible. But not when I put it inside another movieclip.

If I change the alignment of “this.textfield” it works.
But If I put “textfield” in a movieclip called “movieclip” I can’t change it using: “this.movieclip.textfield”

This should work, but it doesn’t

Need more information.
