IFERROR in WPS on Windows FAQ

Last updated:July 23, 2026

When using IFERROR, 3 common issue types include formula errors, parameter understanding, and result refresh behavior; this FAQ includes 3 frequent questions and a glossary.

FAQ

What should I check first if IFERROR still returns an error?

  1. Check whether the formula is written in a Formula field instead of a plain text field.
  2. Check whether the parameter order is correct: the first parameter should be the expression to test, and the second should be the value returned when an error occurs.
  3. Check whether the referenced fields use compatible data types, such as numbers for numeric calculations.

Can IFERROR be used together with other functions?

  1. Write the original calculation formula first.
  2. Put that formula into the first parameter position of IFERROR.
  3. Enter the value you want to show when an error occurs in the second parameter, such as 0, a blank, or prompt text.

Why does the saved formula result still not match what I expect?

  1. Check whether the original formula can return a valid result on its own.
  2. Check whether the fallback value matches the display needs of the current field.
  3. If the result changes unexpectedly with data updates, review the referenced fields, blank values, and calculation logic again.
