Movie Loading a Movie Loading a Movie

Hi there
I have a movie called “main” that loads a movie called “logo”.

In the movie “logo” I have also load another movie called “letter”.

On “main” this is the script that loads “logo”:

this.enabled = false;

On “logo” this is the script that loads “letter:”

this.enabled = false;

Now here’s my question. I want to resize “letter” when it gets loaded and I was able to find this script:

_root.letter._width = 20;
_root.letter._height = 20;

But for some reason it doesn’t work. Does anyone know why?
