When first opened, the space calculator interface only provides a drop-down menu for the 'Building' field. If a location within a building (i.e. Building 1, Room 1, Cabinet 1) does not have a value in the 'Floor' field, it is not possible to calculate the space of a more granular location within that building, as the next drop-down only appears if there is a value in the 'Floor' field for one or more locations in a particular building.
Also, if one location in a building has a Floor value but others do not, it is only possible to calculate the space of a more granular location for the locations which have a Floor value, as the rooms without Floor values do not appear in the Room drop-down (which only appears after a Floor is selected).
As a collection manager, I would like to be able to calculate the space within a room or more granular location even if there is no value in the 'Floor' field.
