Creating running totals for a group
Another common use for running totals is tallying items in a group. The
running total starts with the first item in the group and ends with the last.
Then it starts all over again for the next group, then the next, and so on.

• Groups customer orders and resets the running total for each group.
• Displays the subtotal for each customer group.
