Kangaroo: Solution Exemption: Index out of range

Hello,

Im trying to pull variable springs and points to a mesh, but I keep getting an index out of range error. If I had to guess, I'd think I screwed up the indexes culling the endpoints to be anchors, but Im still new to Grasshopper and Kangaroo, so I dont really know where to go from here.

Ive attached the files... any help would be greatly appreciated!

Thanks!
