Image sampler on a curved surface

Hi there, I am pretty new with grasshopper and I am facing a little trouble with it.

I am working on a facade with image sampler but I'd like to apply it to a curved surface. For now I got this definition which works with planar surfaces only.

How to make it work with curved surfaces?

Give a look at the attached file

Thanks a lot

Thank you for your help. It finally worked out.

The point is that it works with simple surfaces only. When I am setting my surface, which is slightly complex though, an error message comes back:

1. Solution exception:Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

The surface is not very clean. How did you make it? Also, it is a trimmed surface. Rebuild the surface to be not trimmed either by contouring it and lofting or some other operation.
