Select elements of a category of a level

Hello, I’m a beginner in Dynamo and I would to select all floors of a given level from my Revit 3D model. I succeded to select all elements of a level (All Elements at Level), all floors in the model (All Elements of Category), but not all floors of a level. Do you have any idea to do that ? Nico
