Loft problem

[FordEarl]

I am having trouble lofting between two sets of circles.

In this example, there are 53 pairs of curves that i want to loft between each pair.
Can anyone provide any help.

You need to graft each set of curves.

That way grasshopper knows to match Curve 1 from Set 1 with Curve 1 from Set 2.
