Question details
The user wants to prevent an N/A (Not Applicable) radio button selection from negatively impacting a calculated score or average in a PDF form.

- Scenario
- Designing a graded or scored interactive PDF form where users can select N/A for certain questions.
- Observed behavior
- When a user selects N/A, the default calculation treats it as a zero or incorporates it into the denominator, artificially lowering the final average or total score.
Ensure you have access to your PDF in a form editing environment with developer tools enabled, and note down the specific field names of your radio buttons and calculation fields.
Assign a Neutral Value for Simple Total Calculations
If your form calculates a simple sum total, you can assign the N/A option a neutral export value to prevent it from affecting the final score.
When calculating a total score by adding up values, having an N/A option selected will not reduce the score as long as its value is strictly neutral (zero). This method does not require complex scripting.
Open your PDF document and activate the form editing or prepare form mode to reveal all interactive fields.
Right-click the specific N/A radio button you wish to modify and select 'Properties' from the context menu.
Navigate to the 'Options' tab. Locate the 'Radio Button Choice' or export value field and set it to '0' (zero). This ensures that if selected, it adds nothing to the sum.
Open the properties of your total score text field, go to the 'Calculate' tab, and ensure it is set to 'Value is the sum (+)' of your designated question fields.
Use a Custom Script for Average or Percentage Calculations
If you are calculating an average, you must use a custom calculation script to dynamically exclude the N/A option from the denominator.

Frequently Asked Questions
Why does selecting N/A lower my PDF form average?
Standard calculation tools count every answered field to determine the denominator for an average. If N/A is treated as an answered field with a value of zero, it increases the total number of questions divided, thereby lowering the average score.
Do I need to write code to calculate a simple total with N/A options?
No. For simple addition totals, you only need to ensure the N/A radio button has an export value of zero. This can be configured entirely within the basic field properties menu without writing any code.
What happens if all questions on my PDF form are marked as N/A?
If you are using a custom script for averages, you must include logic to check if the valid question counter is zero. Without this, the script will attempt to divide by zero, resulting in a calculation error or a blank field.
