Hard: SUM with wrong absolute anchors

Total uses =SUM($B$5:$B$8) so Travel+Misc are ignored (15249). Fixed =SUM(B5:B10) → 18049 (LibreOffice verified).

About this data: Made-up expenses for Rohan Deshmukh (Nashik) and Sofia Ricci (Milan). Practice only.

Why → What → How

Why: Absolute both ends of a SUM look “safe” but freeze the range when the ledger grows.

What: Broken total 15249. Fixed 18049.

How:

  1. Open Ledger.
  2. Compare B12 to the Expected cell.
  3. Widen the SUM to B5:B10 (relative ends).
  4. Confirm 18049.

Ravindra Bagale’s Tip

Use absolute anchors only for the corner that must not move — or convert the block to a Table so formulas expand.

Bugs explained (with mini examples)

Bug 1 — Double absolute SUM

$B$5:$B$8 ignores rows 9–10.

Bug 2 — Insert mid-block still stuck

Absolute ends do not absorb inserts the way relative table refs do.
