Create Empty movie clip?

yo guys and gals, im trying to get a movieclip to appear when I rollover another movieclip (e.g circle1) using Action Script. I Have tried using attachmovie with semi-luck but was unable to get the imported Movieclip to change it’s position on the stage. So i decided to try and use ‘createEmptyMovieClip’, except when I tested my movie nothing appears when I rollover circle1. I had a look in the debug window and saw that the empty movieclip ‘McB’ is being created when i rollover, so why is it not appearing??

My code is below, so please tell me what im doing wrong and many thanks in advance.

[font=Arial]on (rollOver) {
_root.createEmptyMovieClip(“McB”, 0);
“McB”.attachMovie(“box2”, “box3”, 0);
}
on (rollOut) {
“McB”.unloadMovie();
}
