Display Total Inventory from sum of amounts of logged inventories

I am trying to display the total inventory for a specific item. Currently, as I have it set up it is not working. I’m hoping someone can enlighten me on what I’m doing wrong here haha.



At a glance, I’d try Parent group’s Item’s Inventory’s Amount, but let me know if I’m misunderstanding here, only 1 week into learning bubble :slight_smile:
