Problems working in the y axis

I always hate posting problems like this because I know I'm going to see it as soon as I leave this forum. ok the problem is I'm trying to make a surface from three curves two down and one up like a parabola extruded. the loft command allows me to connect the two on the same plane but not the one above. so I tried to extract the points and use a polyline that I could sweep. same problem. i lofted three curves outside of my definition using GH and it worked so I must have something in my definition that is keeping this from working. if you can take a look I would be grateful. maybe it just needs another set of eyes

It's not a good idea connecting multiple data in Input source that cannot recognize the data structure of each value.

check the definition i ve changed, i used the merge component and you can see these data have different datapath. that was problem.

The solution lies with making sure that the data structures of each element align. Your original curve is {0} and both your modified curves are {0;0}. Therefore the loft component is treating each modified curve as a loft and is looking for more curves for the other original curve hence the error message.

Simplify the data structure of the modified curves and you will get the solution you are looking for.
