Yes, as I thought… you’re referring in your text elements to the Parent Group’s Product… but the Parent Group doesn’t have a product (it’s empty), as you’re not defining it (at least as far as I can see).
You need to define which Product the parent Group is holding - either in the data source, or in some workflow action.
So, as the data source is empty, unless you’re defining the Product in a workflow somewhere, there is no product in the parent group, so nothing will display.
