Container in container

Hi,

On my main stage I load an external swf file into a container named “container”. In this swf file I have buttons to load another external swf file into a container in the first external swf file, named “container2”.
Nothing happens when I push these buttons.

My code for loading the first external swf file:

on (release){
_root.container.loadMovie (“deschool.swf”);
}

My code for loading the second external swf file:

on (release){
_root.container2.loadMovie (“voorwoord.swf”);
}

Can someone help me please?
Thanks

Stefaan
