Carry out this task

  1. Save the Before values on the linked tool.
  2. Append the new counted row and save the same box ID.
  3. Calculate & Save the After values on the same item. Check the ID is retained rather than creating another physical item.

Calculation and observed tool result

Before

Contents rows sum to 2 items. Check each row, unit and packaging.

Recorded quantity: 2 items.

After

Contents rows sum to 3 items. Check each row, unit and packaging.

Recorded quantity: 3 items.

What the result means

The box now contains three items with both categories visible.

Limits of this example

Only physically packed items belong in the contents list.

A mistake to avoid

Replacing the contents field with only the new item would erase the blankets.
