Mc container width and height

is this how i would create a mc container with positioning and width and heigth?

var mc = _root.createEmptyMovieClip(“photocontainer”, 1);
mc._x = 3;
mc._y = 30.5;
mc.width = 440;
mc.height = 345;

Thanks,
Aaron

if it works then yes, if not then sorry no. =) it looks right.
