Splines from Excel Points

I am trying to generate 6 splines based on points from excel file.
I modfiied the node called “Road splines from excel” from BIM4Struc.BridgeDesign package.
The original node generate 4 splines, I would like to generate additional two based on PointCodeMiddleLeft and PointCodeMiddleRight from excel table.
I try to model bridge in revit using dynamo. The workflow is shown as below:

My node for 6 splines:
My excel table:

I would be very obliged for helping me with fixing the node I modified.

I do not currently have that package installed, but you can perform this workflow using OOTB nodes.
(And one Sastrugi node :blush:)
