When using GAMMAINV, common questions usually involve argument errors, unexpected results, and filling formulas across multiple cells; this FAQ includes 3 common questions and a glossary.
FAQ
What should I do if GAMMAINV returns an error?
- Check whether each argument is a valid number and does not contain extra spaces or text.
- Confirm that separators and parentheses are entered correctly.
- If arguments come from referenced cells, make sure those cells are stored as numbers.
Why does the GAMMAINV result look different from what I expected?
- Recheck the argument order and referenced cells.
- Confirm that text-formatted numbers are not being used as numeric inputs.
- Test the formula by replacing arguments one by one to identify the source of the issue.
How do I use the GAMMAINV function in multiple cells?
- Enter the complete formula in the first target cell.
- Select that cell and drag the fill handle across the target range.
- Add
$to references that should stay fixed before filling the formula across more cells.
