Targeting

Hello !
Another problem yet,
I have one MC (mc1) which loads another one (mc2). In mc2 i have buttons that has to load mc3 in Mc1 so here’s the code for the button :
[AS]on (release) {
_parent.bar.content.loadMovie(mc3.swf);
}[/AS]

bar is a mc into mc1 and content is the container.
It doesn’t work, can someone tell me what is wrong with it?
I don’t use _root because Mc1 is loaded into my main movie

Thanks
Ubik
