Sections of Rooms

Hello Revit/Dynamo Community :slight_smile:

I have been working on a workspace that will effectively section every wall of a given room space (ie: In a square room, it would create 4 sections (one on each wall), all with equal spacing from the wall, and spanning the length of the wall). I had seen this idea through a tutorial and have tried to replicate it, but when I go to apply it to my Revit drawing, it doesnt do as intended (as seen in the video).

I have posted my current workspace/tutorial in hopes that the community can identify my problem, so I can move onto my next workspace!
