shifting bricks

Hello - I am trying to shift rectangle geometry based on its relationship to an attractor point/curve. Every rectangle within a given distance should shift the minimum distance defined. Every rectangle over a given distance should shift the maximum distance defined.  Every rectangle between these two should gradate shift between the min and max distance.  I believe I am getting the right integers for these shifts but when I move the geometry it is not showing correctly. The min shift works, The intermediary shift is not, and the max shift is showing with the min dimension.

Please see the attached rhino file, and gh definition. 

thanks for the help!
