Load external swf to a movieClip

Hello everybody!

I wounder if someone could help me with this problom.
I wounder how to load an external swf to a movieClip, not to the _root timeline.

I have this code:

on (release) {
_root.dropZone.loadMovie(“menu.swf”);
}

I use a empty movieClip “dropZone” where the external swf loads to, so far everything is okey. But then when I put the dropZone movieClip in to another movieClip and try to load the swf file nothing happends. The button is in the same movieClip as the dropZone movieClip not in the _root.

I hope someone understand me, and can help me…
