Match Values from 2 (3D Lists) then filter

Hi All, appreciate any help with this, I’m pretty sure something similar has been covered before and I’m happy to be redirected especially as the search function isn’t great on the forum…

I’m trying to filter a list that contains all the values with one that only has a select few. My list management skills are not up to scratch, and it looks as though a dictionary node might work, however no luck so far.

I’ve been able to use list.contains to cross lacing successfully when searching for 1 item. As soon as the list becomes 3Dimensional it fails. sample graph also attached.
