can attractors make influence on the opposite direction?

Dear all,

I make a surface that becomes doubled curved when I place some attractor points.
I have some points on top and some others on the bottom.
I want to have the opposite influence on the top and on the bottom,
I mean, I want the top to have an influence on positive y direction,
but the bottom negative y direction.
I know this is posible if you place f(x) component and for x to put 1/(x).
I'm doing this for the bottom attractors, but it gives an error...

Does somebody know why?
Attached I have the gh file that I'm working on.

thanks for your help in advance :)

    I see that you have some instances of 0 going into the component you have labeled, which in turn asks Grasshopper to divide by 0, which it cannot do. I'm not entirely sure if I understand the objective, but perhaps you want a -x instead of a 1/x?
