Movie doesn't show with attach movie

hello,
I have trouble with attaching a movie, i’ve read the help file and everything i made is what is supposed to be but the movie doesn’t show up, here’s my code
[AS]on (release) {
_parent.container.attachMovie(“att”, “att2”, 10);
}
[/AS]

att is the linkage name, and container is the movieclip where i want to attach my movie (has instance name) and it’s on top layer, i also tried with “this.attachMovie” or “_parent.attachMovie” but still does’nt work.
Can anybody help me ?
Thanks
