Targetting partent mc

Dear All

I have a swf which contains a main menu bar along the top which has been added dynamically at run time. ALl the controls for this bar live inside btnHold

One of these buttons loads in a new swf. There is a button within this second swf that I want to use to control the main menu bar in the top layer (I want to make it invisible for a time, or get its layer and then ensure that its not too high etc etc)

However, I just can’t work out how to target this btnHold from within the newly loaded swf

ANy pointers greatfully received!

thanks

E
