Group Elements by "Phase Created" and "Description"

Revit
1

Trying to get my Elements of a Category, sorted by “Phase created” and secondly by “Description”. Further i would like to (and there’s the Poblem i’m struggling with) Group all Elements of one kind to get the number of Elements. For Example - if there are 3 Elements with the description “Anchors” in a “Phase Created”, than the Output Should be “Phase 1: Anchors 3x” not “Phase 1: Anchor Anchor Anchor”.

(The Python Script just gets the Name of the Phases)

I would appreciate any kind of Solution. Thank you in advance.

Use a List.Count node with the correct Levels and Lacing on the GroupByKey node, and then join that back onto your other information.

Thank you! Worked out great with the clockwork List.CountOccurences node.
