Pull Two Surfaces to Two Separate Curves

Hi,

I am trying to create two separate surfaces from two separate curves defined by two data lists using one curve attractor definition. However, I cant get the two surface to each be unique to each curve, they are just both exactly the same. Is there any way I can separate the data out so one list treat one curve and the second treats the other. I have tried using the partition component but it dost seem to work. I also need the definition to be scale-able, so I can add multiple lists at the beginning. 

Any help would be much appreciated!

Thanks
