[Sidefx-houdini-list] pop previous velocity

Hello there,

I'm trying to cache the particle oldVel (velocity at the previous frame).
I read the upvector node should create a previousVelocity local variable 
(PV) but this doesn't seem to be working properly, in fact PV is the 
same as V.
Do you have any other idea on how to store the oldVel as well?

thanks a lot
