# Answer check — episode 88

Place the three numeric kit counts in B3:B5 and total in B6. The deliberate bad formula =SUM(B3:B6) refers to B6 itself and is circular. The corrected formula =SUM(B3:B5) returns 50. Every source row remains 15, 28 and 7. The exact warning text may vary by Excel version; the formula-bar diagnosis does not require a particular warning dialog.

## Applicability

This lesson uses a direct self-reference in a disposable workbook copy. Desktop Excel documents Formulas > Error Checking > Circular References; Excel for the web may not expose the full tracing menu. Do not claim that a warning always appears, or that iterative calculation is a general fix.

The practice example is fictional. Confirm the current control and result in your own permitted English-language application copy.
