Inverse Scaling. Attractor Curve

Help please!  

This seems like it would be easy but I can't figure it out!  

Currently, I have a shape that's placed on a checkered grid.  The shape reduces in scale the closer it is to the attractor curve. 

What I would like is to do the inverse.  I would like the shape to be the largest as it gets closer to the curve.  I need to also restrict the max & min shape sizing to what I already have on the file.

I've managed to inverse this somewhat, but the shapes closest to the attractor curve are HUGE!

Thanks for your help :)
