setting directory path

Hi – I’m using the Woffice theme and am having trouble trying to add files to subdirectory. Subdirecotry shows up on list, and when clicked is see the main directory and the subdirectory over the table, but subdirectory does not show up in Destination Directory pull down menu. When I try to add files to subdirectory table using the fileup button I get a “Please build the path to your destination” message. I’m a noob sorry.
