Furniture Family - Dimension by references graph not working

The graph is not working for furniture family.
Please advise what am i doing wrong or how i can fix it.

I am trying to achieve dimensioning each furniture individually and automatically using the Left and Right Reference. Can this graph dimension all different kinds of furniture together or only several instances of one type of family.

This is the first step , after this i want to be able to automatically dimension every furniture on every level on two sides. I would appreciate any guidance on this too.

Got it to work finally. It was an adjustment in list lacing. And can dimension multiple family objects on that line!
