There is too much floor and ceiling area ...

[ytun054]

SO i'm getting this error. I'm not sure what to do. I've actually fixed the errors shown in the export menu. Can anyone help ?

Invalid gbXML file:
There is too much floor and ceiling area in the gbXML file received by Green Building Studio: Floor and ceiling area = 11,270 m2Building area = 6,621 m2The floor and ceiling area must be within 20% of the building area to perform meaningful energy analysis.
Note: Typically this problem occurs when room or space objects are not properly defined in your Revit model. Check that all interior volumes in your model contain room or space objects that are fully enclosed by floors, walls, roofs or other room bounding elements. See Using Green Building Studio with Revit Architecture and Revit MEP for helpful details on room and space objects. To inspect the analytical model of the gbXML file in Revit 2010, click Export > gbXML on the Revit application menu and explore the details tab.
