Tidy (order) a list of points in a curve

Hi, I’m getting this list of points as an intersection between the vertical planes at the bottom and the horizontal nurbs curves. I’d like to get the indexes of points, following a continuous path through the nurbs curve (from a beginning to an end) but Dynamo creates them alternatively at both sides. Any ideas? Any help would be appreciate. Thanks!

Maybe use the ParameterAtPoint node to get a list of the parameter values of the points and the use List.SortByKey node with the parameter values as keys and the original points as the list input.

OK, it worked! (levels) Thanks a lot.I’ve always used PointatParameter, no ParameteratPoint.
Thanks a lot!
