- Scenario
- Creating or processing a PDF questionnaire that requires automatic tallying of categorical responses into summary fields.
- Observed behavior
- The form needs a mechanism to dynamically sum up the export values of selected radio buttons and display the counts for each category.
Ensure your PDF form fields are properly named and grouped, and that you have a PDF editor that supports custom JavaScript for form calculations.
Use Custom JavaScript in PDF Form Calculation Fields
Add a custom calculation script to a summary text field to iterate through the radio button groups and count the selected values.
To count specific text values like 'Yes' or 'No' from radio buttons, standard built-in calculation functions (like SUM or AVERAGE) are not sufficient. You must use a document-level script or apply a custom JavaScript snippet directly to the calculation properties of your summary text fields.
Use your PDF form editing tools to add plain text fields to your document where the final totals for 'Yes', 'No', and 'N/A' will be displayed. Name them clearly, such as 'Total_Yes'.
Right-click the newly created summary text field (e.g., 'Total_Yes') and select 'Properties' from the context menu.
Navigate to the 'Calculate' tab in the Properties dialog box, select the 'Custom calculation script' option, and click the 'Edit' button.
In the JavaScript editor, write a script that loops through the document's radio button fields, checks if the export value equals 'Yes', and increments a counter variable. Assign the final count to the current field using 'event.value = counter;'.
Repeat this process for the 'No' and 'N/A' summary fields, adjusting the export value check in the JavaScript code to match the respective category.

Frequently Asked Questions
Why isn't my PDF form calculation updating automatically when I click a radio button?
Form calculations trigger based on field calculation order. Ensure your summary fields are set to calculate after the radio buttons are selected by checking the 'Field Calculation Order' in your PDF editor's form settings.
Can I use checkboxes instead of radio buttons for this calculation?
Yes, but checkboxes allow multiple selections per question. If you need exclusive 'Yes', 'No', or 'N/A' answers for a single question, radio buttons with the same group field name and different export values are required.
Do I need coding experience to calculate PDF form totals?
Basic calculations involving numbers (like sum or product) do not require coding. However, conditional counting—such as tallying specific text values like 'Yes' or 'No'—requires writing a short JavaScript snippet in the field's calculation properties.
