Sinc three lists to interpolate curve

Hi there, I am having trouble to sort 3 points (start, middle, end) so they can made a nurb curve or interpolate them… they seem ok in the list organization but even if i separate those points individualy with list item component I cant generate the nurbs or interpolate curve because it is saying that the number of points are insuficient… Anyone know how to solve this?mesa de (14.4 KB)

Hey, it was due to data matching. Flatten and Merge would help.

something that is bugging my mind is that, why mergin the points goes good while when i do the entwine between the lists it doesn’t?
