Folder priviliegs


i am currently setting up my directory topology but i run into a little problem:
I have a group named: office and a folder named organization with the subfolders: finances and it;
Now I would like to set the permissions so that the group Office can see the folder Organization with all subfolders but can only read and write in the financial folder.
Anyone knows how i can realize that?

Thanks dfresh

any possiblity to do that?
