DIVA / Surface Analysis Point values / List selection

All,

I'm attempting to use Diva's surface analysis to drive a set of facade geometry. At this point DIVA is giving me nice, clean analysis values across the object (many points). I am starting with a floorplate perimeter curve, breaking this into several points and then attempting to find the closest analysis value from DIVA.

Once the closest analysis point is found (no problem here), I am planning to take the VALUE of the same point and use it to modify the move/modify the floorplate points.

However, I'm having issues pulling the closest analysis values from the entire list of analysis points... I'm getting something, but the values are not correct or in the right order. It's a mess.

RED = DIVA based points / info

BLUE = RHINO geometry / points.

I suspect I'm messing up in splitting/sorting/dispatching the 'closest points' from the complete list of DIVA points. Hard to see, but the analysis points are all in the range of ±900 on the nearest side... and the blue 'selected values' are coming back at ±200. They should be the same as the nearest analysis value!
