How to Fix an Acrobat Dynamic Stamp Showing Only One Field
Question details
The user needs to fix a custom Adobe Acrobat dynamic stamp that fails to display all selected checkboxes, text fields, and prepopulated names, showing only the date and one selected value instead.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Using a custom dynamic stamp with JavaScript to process form inputs like radio buttons and text fields.
- Observed behavior
- The dynamic stamp only displays the current date and a single selected value, ignoring other checkbox selections, entered text, and prepopulated names.
Before modifying your dynamic stamp, ensure you have a backup of the original PDF stamp file and access to a PDF editor that supports JavaScript execution and form field editing.
Verify and Correct JavaScript Field Names in the Stamp
Ensure that all form fields in your dynamic stamp dialog match the exact names referenced in your JavaScript code.
Dynamic stamps rely on JavaScript to pull data from form fields. If the script references a specific field name, the actual form field in the PDF must match it perfectly. Discrepancies in naming or grouping will cause the script to fail partially, resulting in missing data on the stamp.
Locate and open the source PDF file of your custom dynamic stamp in Adobe Acrobat using the Prepare Form mode.
Inspect the properties of your radio buttons. For the existing script to work properly, ensure each radio button in the targeted group uses the exact name 'Action' (or the specific name required by your script).
Confirm that radio-button fields and text fields are configured as entirely separate field groups. Verify that their export values and naming conventions meet the script's length and format requirements.
Open the JavaScript editor for the stamp to cross-reference the exact string names used in the code with the actual field names on the PDF form. Save the stamp and test it again in a new document.

Frequently Asked Questions
Why does my Acrobat dynamic stamp only show the date?
This usually happens when the JavaScript powering the stamp encounters an error or cannot find the referenced form fields. If field names like checkboxes or text inputs don't exactly match what the script expects, they will fail to populate, leaving only default elements like the date.
Do field names in a PDF dynamic stamp matter?
Yes, field names are strictly case-sensitive and must be referenced accurately in your JavaScript code. If a radio button group is named 'Action' in the script but 'action' on the form, the script will break.
How do I group radio buttons in a PDF form?
To group radio buttons so that only one can be selected at a time, you must assign the exact same 'Name' to all radio buttons in that group, while giving each a unique 'Export Value' in the field properties.
Can I edit the JavaScript of an existing dynamic stamp?
Yes, if you have access to the original source PDF of the stamp. You can open it in a PDF editor that supports form editing, access the Page Properties or field calculation scripts, and modify the JavaScript code.
