This FAQ covers 3 common BESSELY questions, focusing on error handling, result checking, and filling formulas across multiple cells.

FAQ

What should I do if BESSELY returns an error value?

  1. Check whether the formula begins with =.
  2. Make sure each parameter is a valid numeric value and does not include extra spaces or text.
  3. Confirm that parameter separators use English punctuation.
  4. If needed, re-enter the parameters through the Insert Function dialog box and confirm again.

How can I troubleshoot a BESSELY result that does not match my expectation?

  1. Check whether the referenced cells or parameter values are correct.
  2. Make sure related cells are not stored as text; if needed, change them to a general or numeric format and enter the formula again.
  3. Review the formula in the formula bar to confirm that no parentheses or parameters are missing.
  4. Compare the current formula with the syntax guidance and adjust it as needed.

How can I use BESSELY in multiple cells?

  1. Enter and confirm the BESSELY formula in the first target cell.
  2. Select that cell and move the pointer to the fill handle in the lower-right corner.
  3. Drag the fill handle down or across to copy the formula to other cells.
  4. Check whether relative references behave as expected, and use $ if you need to lock a reference.
