FAQ

Last updated:July 8, 2026

This FAQ covers 3 common issue types for BESSELI in WPS: parameter errors, unexpected results, and repeated fill tasks.

FAQ

Why does BESSELI return #VALUE! after I enter the formula?

  1. Check whether each parameter is numeric instead of text.
  2. Check whether the parameters contain spaces, non-English punctuation, or other invalid characters.
  3. If needed, clean the original data first and then enter the formula again.

What should I do if the BESSELI result does not match my expectation?

  1. Check whether the cell references and parameter order are correct.
  2. Confirm that related cells are formatted as numbers instead of text.
  3. Use formula checking tools in the Formula tab to inspect the calculation step by step.

How can I use BESSELI in multiple cells at once?

  1. Enter and confirm the BESSELI formula in the first target cell.
  2. Move the pointer to the fill handle at the lower-right corner of the cell.
  3. Drag downward or sideways to fill the formula into the target range, or copy and paste it into another area.
  4. When filling across multiple cells, check whether relative and absolute references are set as expected.
