Problem with curved wall / rebar script

Hello,

I am trying to make a script that will create rebar in a curved wall by adding horizontal and vertical bars but I’m not sure if I am the right tracks with it or not ? when I added the “Surface.PointAtParameter” node i expected it to give me points around the top and bottom of the wall but it does’nt appear to do that.
