Data Collection issue

I am creating a surface that moves based on the evaluation of a point along a curve.  That surface has a series of circles that pull points from the original offset moving surface down to an "anchor".

I have been able to get one instance of a pull condition, however I cannot seem to be able to add multiple curves to the the definition that all equally pull. 

I think that the issue is witht he data collection, that there needs to be two translation vectors instead of one from the circles to the array of points that are pulled and then moved along with the rest of the surface.

Any suggestions?
