HI as depicted on the picture I have a sublist called Expense and another called Items. Both contain fields called Amount. I’m trying to implement another field and insert a formula referencing Amount from the Expense sublist because when I do {amount} / {quantity} it does not work at all so I believe due to conflict. How do I reference the one from Expense side thanks

In the UI ; No quantity & rate fields on your form? NetSuite will calculate Amount base on qty * rate. However, you can enter what ever number you want in the amount field. NetSuite will throw a pop up that the amount does not match qty & rate. Don't know the answer to the question of 'pulling expense' the invoice total will be the total of item & expense
