Carry out this task

  1. Create or open the Before record on the linked tool.
  2. Save the updated loose count and explicitly rebuild the label.
  3. Check the saved After values before downloading the rebuilt label. Replace the older physical label.

Calculation and observed tool result

Before

1 × 4 + 2 = 6 rolls

Recorded quantity: 6 rolls.

After

1 × 4 + 1 = 5 rolls

Recorded quantity: 5 rolls.

What the result means

The replacement snapshot carries five rolls rather than six.

Limits of this example

The old label remains readable until physically removed.

A mistake to avoid

Reprinting an old downloaded PNG would preserve the obsolete count.
