How do I create panels (surfaces) from a grid of curves or points?

I have uploaded a file for clarity. I have a grid of curves, and a grid of points, but I don’t know how to turn either of these into a grid of surfaces (panels). I have tried the LunchBox panel tool, but I want the heights of the horizontal curves to remain like this. I am quite new to Grasshopper, so any help would be appreciated.
