Data conversion failed from Curve to Surface (Parametric Facade Issues)

Good evening, or morning lol. I am an architecture student working on a project for tomorrow and this is my first real time using Grasshopper. I am working on making a parametric facade and having some difficulty getting my profiles to properly align on my curve for the structure. I have so far been able to get the code correct except for this one data conversion error. Would anyone be able to help? I have attached photos, my files, and an image of what I am trying to get to. The reason I have the section profiles done the way I did is so that I can go back and change them easily as the design evolves.
thanks in advance!

Brep/Brepwon’t work if you intersect a brep with planes fromPerp Frames. Use Brep/Plane instead.
