Revit Society

ok, so i draw a square on level one and click 'create form'. i now have a 6 sided box. if i want to add an edge i click 'add edge', same with 'add profile'... but my problem is i can only add edges and profiles to vertical faces, no watter what i try i can't get seem to add an edge to a horizontal face (even after setting the horizontal face as the working plane). am i missing something or is it not possible to add an edge to a horizontal face?
