Here's an example of what i think you are trying to achieve. You need a starting position for the point you are moving. When you move the point you create a vector from starting position to the new position. This vector is used to move the referenced point in the curve. In this example i used (0,0,0) as the starting position of the point, so the point coordenates correspond to the vector.

There's a new component now called "List Replace" that allows you to do this in a simpler way:

They are much better now, the simpler the better.

With any luck the next thing to go are the bevels and highlights. David should go full metro, it might annoy some Mac users though.

The "replace members" component in this case is a bit worse alternative since you already know the index you want to replace so you are making the computer work harder than necessary. Also, you might have self intersecting or closed curves and end up moving more points that you want.

You're missing the move component.

was just a quick alternative to show a different component, nothing more :) If it exists its okay to also explore it.
