Common mistakes in sample input

Using a column that does not exist

Fix: Check the TSV header or use a valid 1-based column number.

The replacement values count does not match the row count

Fix: Provide one replacement value for each TSV data row.

Forgetting the blank line before the TSV body

Fix: Put selector, new header, and values first, then a blank line, then the TSV.
