Dynamo Civil3D - Create Corridor Help

I am getting mixed results with this graph.
I am getting errors.
It works on some files when I reduce the quantity of baselines.
It doesn’t work on files with large quantity of baselines.

I don’t think I have my lists formatted properly.

Thanks in advance to any kind folks that might be able to review the graph and comment.
