So, I have created a value list which contains the monetary value of all orders (in table "orders") and set it to include only related values starting from the related table "customers".
Each order in the table "orders" is assigned to a customer with a unique ID, which is the UID in the table "customers".
Now what I want is to display the sum of the monetary value of all orders made by each of the customers.
How can this be done? All help would be greatly appreciated!
