Quick fix
Symptom: A DAX measure returns BLANK instead of a number.
Most likely fix: Check filter context, relationships, missing data, and whether DIVIDE returns alternate results.
Step-by-step checks
- Confirm the formula, column, measure, or range where the issue appears.
- Check whether the source values are numbers, text, dates, blanks, or errors.
- Test the formula on one simple row so you can isolate the logic.
- Remove extra wrappers like IFERROR temporarily so the original error is visible.
- After the formula works, copy it to the full range and check totals.
Common causes
- Mixed data types, such as numbers stored as text.
- Hidden spaces or inconsistent spelling in lookup values.
- Wrong relative or absolute cell references after copying formulas.
- Ranges that do not cover the full dataset.
