Setting the position and angle of an actor to that of another actor

Hi there, just starting out so sorry for the dumb question. Just wondering why this simple set up won’t work. I am trying to set the angle and position of the cylinder to that of the cube always.

Thanks for the help.

Why not just make them the same actor if that’s what you want? Why waste processing power constantly setting them together? Also what isn’t working? What happens exactly?
