Flash CS4 - Can't find hidden menu in my file

Hello,

Im still learning flash and the flash website im trying to update was done by some one else.

The menu in the homepage all the links have similar script on it like below only changing offcourse the swf and then the one im having a problem with the menu_mc.gotoAndStop(5);

This link cursos.swf points has the menu_mc.gotoAndStop(5); just like below.....

but another link on the home page will have a differnt swf and a menu.mc.gotoAndStop(3) for example only changing the final number..... but I looked everywhere and cannot find any menu.mc anywhere....








on (release)
{
loadMovie("principais/cursos4.swf", loader);
gotoAndStop("vazio");
menu_mc.gotoAndStop(5);
}
