Encountering errors with PivotTables can be frustrating, but many common issues have straightforward fixes. Here's how to troubleshoot some of the most frequent PivotTable errors:

1. Blank Cells in PivotTable:

* Cause: Source data might lack entries for specific subtotal combinations.
* Fix: Go to PivotTable Analyze tab > Change Field Settings > Show Empty Cells As > select "0" (or a preferred value) to display zeros instead of blanks.

2. PivotTable Field Name Not Valid:

* Cause: Missing or blank header cells in your source data.
* Fix:
- Check your data source for missing headers and add them if necessary.
- Ensure no hidden columns exist that might be causing issues.

3. PivotTable Refresh Errors:

* Cause: Inconsistent data formatting, formula issues, or external data connection problems.
* Fix:
- Verify consistent formatting (e.g., dates) between source data and PivotTable.
- Check formulas in your source data for errors.
- Refresh external data connections if applicable.

4. PivotTable Data Doesn't Match Source Data:

* Cause: Incorrect source data range selection or hidden rows/columns.
* Fix:
- Double-check the PivotTable settings to ensure the correct data range is selected.
- Unhide any hidden rows or columns in your source data that might be affecting the results.

5. Cannot Hide Selected Items:

* Cause: The "Enable selection" option might not be turned on.
* Fix: Go to PivotTable Analyze tab > Change Selection > Enable selection. Then you can right-click and hide selected items.

6. Limited Functionality with Dates:

* Cause: Dates might be stored as text instead of actual date values.
* Fix: Use the TEXT function to convert your text dates into a recognizable date format (e.g., YYYY-MM-DD) before creating the PivotTable.

These are just some common errors. If you encounter something different, it's helpful to consult Excel help resources or search online for specific error messages.
