Closing a polyline (loop)

Hello everyone,

My name’s vincent and I am trying to learn Grasshoper.
After a few tryout following video tutorial, I am now trying to build thing by myself, and after 20minutes my first unsolved problem showed up.

I’am tryin to create a polyline ( star shape) going throught points from 2 differnet circle. But my line is not closing / ending on the point where it started. So Iam missing a segment to get a “star”.
Is it my process, or are they some settings I’ve put wrong?
Would it be somethign about “looping” my list?

Thanks for your help! (12.8 KB)
