Carry out this task

  1. Save the Before values on the linked tool.
  2. Add the delivered full bottles to the existing record.
  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

Stock = 0 × 300 + 60 = 60 ml; floor(60 ÷ 15) = 4 treatments

Recorded quantity: 60 ml.

After

Stock = 2 × 300 + 60 = 660 ml; floor(660 ÷ 15) = 44 treatments

Recorded quantity: 660 ml.

What the result means

The total becomes 660 ml, enough for forty-four entered treatments.

Limits of this example

Only identical formulations and sizes belong in this record.

A mistake to avoid

Do not replace the open remainder with full-bottle capacity.
