Hey Rob, is there a possibility that you can explain how you did the cart?
I am working on a project where I need to have a cart function and the whole thing is going over my head.
I am guessing you have a rule in an action to check if the user has an open order or not. If they dont - it creates a new order and adds a line item and if the user does - it just adds the line item with the order number as relation.
I dont understand the structure of the relations completely. So could you maybe explain that?
