How to Use Radio Buttons for Numeric Values in PDF Forms
Question details
The user needs to configure a PDF form so that selecting specific multiple-choice options populates corresponding numeric or monetary values (e.g., $210,000 or $75,000) for calculation purposes.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating an interactive PDF form where user selections determine specific currency or numeric values for an automated total calculation.
- Observed behavior
- Needs to know the correct form field type and property settings to pass specific numeric values to a calculation field based on the user's choice.
Ensure your PDF editor supports interactive form field creation and calculation properties, such as Adobe Acrobat Pro or WPS Office Premium.
Set Up Radio Buttons with Numeric Export Values
Use a grouped set of radio buttons instead of checkboxes and assign specific numeric export values to each option for accurate calculations.
When you need users to select only one option from a list (e.g., High, Medium, or Low) and have that choice correspond to a specific number, radio buttons are the correct tool. Checkboxes are independent, whereas radio buttons with the same group name act as mutually exclusive choices.
Insert a group of radio buttons onto your PDF form. Ensure all buttons that belong to the same category share the exact same 'Group Name' so that only one can be selected at a time.
Right-click on the first radio button in the group and select 'Properties' from the context menu.
Navigate to the 'Options' tab in the Properties dialog. In the 'Radio Button Choice' or 'Export Value' field, enter the desired numeric value (e.g., type 210000 without the dollar sign or commas).
Repeat the previous step for each radio button in the group, giving each its respective numeric value (e.g., 75000 for the second option).
Create a separate Text Field to display the final currency. Open its Properties, go to the 'Calculate' tab, and configure it to read the value of your radio button group name.

Frequently Asked Questions
Why should I use radio buttons instead of checkboxes for numeric values?
Radio buttons are designed for mutually exclusive choices, meaning a user can only select one option per group. This ensures that only one numeric value is passed to your calculation field at a time, preventing overlapping math errors that can happen if a user selects multiple checkboxes.
Why isn't my calculation field updating when I select a radio button?
Ensure that your export values are strictly numbers. Do not include dollar signs, commas, or letters in the export value field, as the calculation script cannot process them as math. Also, verify that the calculation field is referencing the exact Group Name of your radio buttons.
Can I make a default selection for the radio button group?
Yes. In the form editing mode, you can simply click on the radio button you want to be the default to select it. When you save the form and exit editing mode, that button will remain selected as the default starting value.
