Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification Confirmed errors: Note from author: My explanation in the text doesn't cover non-English language configurations, so I think it's worth a note: If your computer's default language setting uses commas to indicate decimal values (e.g., 3,5 which is written in English as 3.5), you might encounter problems using the INDEX formula described on page 84. The trick is to change the commas to semicolons. In English, an INDEX formula should be written using the syntax INDEX(reference, row_num, column_num, area_num). In a European language, or other language that uses a comma as the decimal separator, try the syntax INDEX(reference; row_num; column_num; area_num). The INDEX formula is part of the broader LOOKUP family, which includes VLOOKUP and HLOOKUP. You can type decimal values directly into a VLOOKUP formula. In most European countries, you would write the decimal value for "three and a half" as 3,5 (as opposed to 3.5 in English-speaking countries), so using a comma as a decimal separator would change the formula =VLOOKUP(1.5,A2:C10,2), which has the correct number of arguments (three), to =VLOOKUP(1,5,A2:C10,2), which has an incorrect number of arguments (four).
