# Independent answer check — episode 135

The supplied `vlookup-practice.xlsx` starts with P-107 in E2 and `=VLOOKUP(E2,$A$2:$C$6,3)` in F2. The exported workbook's cached result is $3.25 from P-106, the preceding code in the sorted source table. After replacing F2 with `=VLOOKUP(E2,$A$2:$C$6,3,FALSE)`, P-107 should return #N/A. With the same corrected formula, P-104 should return $8.75 from its Binder row. A missing-code error is a correct warning, not a price.

1. Missing P-107 is a test case, not a product.
2. P-104 exists; P-107 does not.
3. Omitted means approximate, not exact.
4. P-107 must not display a price.
5. Source row and result agree.
6. Missing code is reported, not guessed.
7. Do not claim FALSE fixes every wrong value.
8. Positive P-104 must still return $8.75.

**Evidence limit:** The exported workbook was structurally checked for the five exact product rows, E2, F2, and the $3.25 cached starting result; its initial appearance was visually reviewed. Microsoft's VLOOKUP documentation supports the formula behavior. The final corrected calculation and displayed cells still need checking in Excel.

**Failure branch:** FALSE prevents an approximate neighbor price; it does not solve duplicate product codes, wrong return-column indices, spaces or type mismatches. Do not replace a missing code with a fabricated price.
