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?
- Check whether the formula is written in a Formula field instead of a plain text field.
- 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.
- Check whether the referenced fields use compatible data types, such as numbers for numeric calculations.
Can IFERROR be used together with other functions?
- Write the original calculation formula first.
- Put that formula into the first parameter position of IFERROR.
- 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?
- Check whether the original formula can return a valid result on its own.
- Check whether the fallback value matches the display needs of the current field.
- If the result changes unexpectedly with data updates, review the referenced fields, blank values, and calculation logic again.

|---|---|
| IFERROR | An error-handling function that returns a fallback value when an expression evaluates to an error; otherwise, it returns the original result. |
| Formula field | A field type in a multidimensional table that is used to enter and calculate formulas. |
| Fallback value | The value returned to replace an error result when the original formula fails. |
