need help with Cull

I'm trying to finish the TUDelft tutorial number 2 (http://wiki.bk.tudelft.nl/toi-pedia/Tutorial_2_-_Surface_Manipulation)

I am stuck on step 4. I can't seem to Cull the last arc in the list. The slider changes the number of arc's, and you are supposed to delete the last one. Then of course the last step would be the loft, I can't seem to get the arcs and the lines to loft either...

Can you tell what I have done wrong in my Grasshopper definition? Thanks!

Grasshopper file and Rhino file are attached.

The problem seems to be in the Cull for the arcs. In the attached image I highlighted the two Culls. When I select the bottom one, which is a Cull for the lines, the lines are highlighted in green in the Rhino model. When I select the Cull on top for the arcs, nothing is highlighted in green in the Rhino model...

I don't know if this is how the tutorial was proceeding. I'm on my way out and didn't have time to look at it. (I had to split this into two posts...couldn't get the cursor to show up after posting the screenshot.)

Thanks Chris. Thats the idea! It's a little different than the tutorial which is fine, we're getting the same results. The first time I did your fix the last arc and line aren't lofting and the first line and arc are:

So I tweaked it a little more, and got the one end to look good, but I'm not sure why I don't get the other end to work right:
