Question details
The user needs to update existing figure or table captions in a Word document to include chapter numbers, typically after merging multiple documents.

- Device & OS
- not provided
- Scenario
- Formatting a merged or compiled document where the existing captions now require corresponding chapter prefixes to maintain sequential accuracy.
- Observed behavior
- Existing captions do not reflect the chapter numbers, requiring manual adjustment or a bulk update using field codes and numbering settings.
Ensure that your document uses proper built-in heading styles (such as Heading 1) for your chapter titles, as the caption tool relies entirely on these styles to generate chapter numbers.
Update Caption Fields with the Refresh Shortcut
Configure a single caption correctly and use the 'Update Fields' shortcut to apply the new numbering logic throughout the document.
This is the most straightforward method for updating captions that were originally generated using the built-in caption tool.
Insert a new caption or modify an existing one. In the Caption dialog, click on 'Numbering', check 'Include chapter number', and select the appropriate heading style.
Press 'Ctrl + A' on your keyboard to select the entire document, which highlights all text and objects.
Press 'F9' to update all field codes. This action will refresh all the existing captions to include the newly configured chapter numbering format.

Use Find and Replace for Advanced Field Code Updates
If standard updating fails, you can reveal the underlying field codes and use the Find and Replace tool to correct the SEQ fields manually.

Frequently Asked Questions
Why is the 'Include chapter number' option grayed out in the Caption dialog?
This usually happens if you haven't applied multi-level list numbering linked to built-in heading styles (like Heading 1) for your chapter titles. Set up a numbered list for your headings first.
Can I update captions for both figures and tables at the same time?
Yes, pressing Ctrl+A followed by F9 updates all dynamic fields in the entire document simultaneously. This includes figure captions, table captions, and your Table of Contents.
Why do my captions show 'Error! No sequence specified' after updating?
This error occurs when the SEQ field code is broken or refers to a sequence identifier (like 'Figure' or 'Table') that doesn't exist in the document. Revealing field codes by pressing Alt+F9 can help you spot and fix typos in the sequence identifier.
