List problem


I wanted to know if someone maybe saw a problem with my lists that are making points move more times than expected making them repeat themselves.

I have a group of lines that have points on them and i want to move those points perpendiculary to the line. Those points after being moved are projected to the xy plane and then i do a line from the original points to the moved points which are now projected to xy plane. But the points are moved more than one so i end up with multiple lines per group of points. im including pics and the gh definition. Its quite long, so youll have to move to the right A LOT and youll find a draw arrowed pointing at the problem.
