Thank you 
We have to drag out from the pin on the “Analysis Beautifier” reference, then we can find Smoothed Values in the list. The smoothed values are inside the analysis beautifier BP, so without a reference to it, they don’t exist.
Once we have the array of smoothed values, we can drag off from that, and then find “get a copy” in the list! We have to drag out from arrays to have the “get” node because it’s function is to get something specific from a list(array).
