Hints to get you started

  1. Use the fourth XLOOKUP argument.
  2. This SKU is intentionally absent.
  3. Set the fallback to "Not found".
Show the worked solution
=XLOOKUP("XX-99",A2:A7,E2:E7,"Not found")

A fallback makes a missing item understandable without hiding the intent.

Make the skill stick

After solving the task, explain what each reference does and why the formula answers the business question. Try the workbook download inside the quest to practice in your own spreadsheet app.
