Changing nested families materials

Hi guys,!

I’m trying to change a parameter (material) of a nested family, but it seems I’m missing something…

The family itself is a series of books (each one is the same nested family varying in width). I would like to apply different materials to these nested families.

Any ideas?

Thanks!
