Problem when trying to unload a mc from itself

Hi guys,

I’ve been trying to solve this problem with a unloadMovie action with no results.

I’ve got a main.swf wich loads a big_pic.swf into a mc with the same name.

The problem is that want to make big_pic unload itself and for that I have a button with the following actions on it:

on (release) {
_root.big_pic.unloadMovie();
}

I’ve tried several other ways using the unloadMovie command, all of them failed.

Is there a way to this at all?

Thank you all in advance.
