Total what a customer still owes, and what's overdue
SUM answers one number. SUMIFS answers "sum this, but only where these conditions hold."
Task:
You handle accounts receivable for a small design studio. Eight invoices sit in front of you, each with a customer, a status and how many days overdue it is. In E10, total how much Bramwell Foods currently still owes — their open invoices only. In E11, total the amount of every open invoice that is more than 30 days overdue, across all customers.
