Hi, I´m having problems with the following…

I have a main swf and an external swf that is loaded onto \_level1  
In the external swf there is a button with the following code…

Pieza01.onRelease = function(){  
\_level0.\_visible = false;  
};

Which works fine.  
But if i replace it with the following code…

Pieza01.onRelease = function(){  
\_level0.menu\_mc.\_visible = false;  
};

Nothing happens, and I´m sure the instance name “menu\_mc” is correct.

Any ideas?  
Thanks a lot.
