Passing a List to Group.FromElements

I’m lost trying to build up a Group.
I’ve got a list of a list of Elements and one of Group Names,
If I pass the each List, I just get an empty list for a result.
If I try to Flatten the first list, the Group.FromElements node tries to put everything in one Group.
I need to pass a list of lists, and have each top-level list create a Group
What am I doing wrong? (I must admit, Lisp.Map still makes my head hurt)

Hi DaveP,

Try using along with “List.Combine” node.
