@RakeshK17503889 I digged into this further and defined a field and this step was missing on the video walkthough. Can someone please confirm if this is the right way to approach this?

This happens because TotalTransferAmount does not exist in the same class as your Review transfers view, so the expression picker cannot see it. Open the Transfers case type, go to Data model, add a field named Total transfer amount as Currency, set Calculation to Use expression, and configure it to sum the Amount of the Transfers list or enter @SumOfPageListProperty(.Transfers(),"Amount") if the UI asks for a function. Save the case type. Open the Review transfers view for the same case type, click Add, choose Fields, and select Total transfer amount; if it does not show, use Create new field in the picker so it is created in the case class. Confirm the view’s data source is Primary set to the case, not a data object page. Check in and hard refresh the browser to clear cache. If you created the field under the Transfer data object by mistake, recreate it under the case class. Now you can reference .TotalTransferAmount in Use expression for visibility or display and complete US-005.
