Lofting curves in a given order

Hi!

I am having some trouble with Loft. I have a set of points that describe curves and that eventually render 10 curves that are to be lofted in two groups of 5. I've found that for one of the groups the lofting worked well after I've used Flip on two of the curves and as long as I plug the curves into the Loft component in the right order. However, for the other group that doesn't work, regardless of flipping and order. Therefore I tried sorting the curves in various ways, but I still can't manage to get it to work.

In each of the two groups, or two sides of the model, I want the top curve to loft to the curve below and so on until the second curve from the bottom is lofted to the bottom curve and a surface is created.

Thanks!
