2. Enter the correct parameter values.
3. Check that separators between parameters are correct.
4. Press Enter to confirm the formula.

Success Criteria

3. Use IFNA with cross-sheet references

Entry point: formula bar

1. Select the target cell and type =IFNA(.
2. In the first parameter, enter a cross-sheet reference or a formula that includes one.
3. In the second parameter, enter the text or value you want returned.
