Common questions about the ISNA function in WPS usually focus on result meaning, argument setup, and batch use; this section covers 3 frequent questions.
FAQ
What does it mean when ISNA returns TRUE?
- Check the argument inside
ISNA(). - If that argument is
#N/A, or it refers to a cell whose result is#N/A, the function returnsTRUE. - If the argument is not
#N/A, the function returnsFALSE.
Why does the ISNA formula not return the result I expected?
- Confirm that the argument points to the correct cell or formula result.
- Check whether the error you want to identify is really
#N/Arather than another error such as#VALUE!or#REF!. - If you need to handle other error types, adjust the formula logic or use a different function.
How do I use ISNA in multiple cells at once?
- Enter
=ISNA(...)in the first target cell. - Press Enter to get the result.
- Select the cell and drag the fill handle, or copy and paste the formula into other cells.
- Check whether you need absolute references with
$.
