1. Flatten your list of curves (looks like you have a nested list of curves)

2. Set the lacing of Curve.PointAtParameter to cross-product (otherwise you’ll only get 1 point per curve)

(Alternatively - if you only have 1 curve in your list, you can just pass that single item and don’t need to change the lacing)

Well, you’re not following it entirely since you have used a different node for obtaining your selection. This node will return a list of elements which will in turn rresult in a list of lists once you use Element.Geometry on it.
