Attractor points in a surface

Hey! i’ve been doing a folding chair project in grasshopper and i’m trying to put attractor points in a surface grid but i can’t. it seems that i only could do it in a planar grid. what i’m trying to do is put circles in this surface/grid so’ll have different circle size with the attractor points in my surface. i dont’ want hexagons, that’s why i haven’t used the hexagon grid.The second image is what i get i don’t know what i’m doing wrong. cause i have fail data in the map too. something is not working and i don’t know what is it. please if anyone know how to do this will help me so much
