How to Add Checkbox Prices and Control Radio Buttons in a PDF Form

Product: PDF Form Editor
Device & OS: not provided
Scenario: Creating an interactive PDF form for event registration or ordering that requires conditional logic and automatic calculation.
Observed behavior: Requires setting up export values for checkboxes to act as prices and using interactive logic to control the visibility of a radio-button group.

Before you start

Ensure your PDF editor supports form field creation and interactive actions, and verify that you have finalized the layout of your checkboxes and radio buttons on the document.

Solution 1Recommended

Calculate Totals Using Checkbox Export Values

Assign a monetary price to each checkbox so that a total text field can automatically calculate the sum of selected items.

By setting the export value of a checkbox to a numerical value, you can treat checkboxes as add-on prices in order forms. A separate text field can then be configured to sum up these values automatically.

Open Checkbox Properties

Enter form editing mode, right-click the target checkbox, and select Properties to access the field settings.

Set the Export Value

Navigate to the Options tab in the Properties window and enter the specific price or numeric value in the Export Value field.

Configure Total Calculation

Create a new Text Field for the final total. Open its Properties, go to the Calculate tab, choose 'Value is the sum of the following fields', and select your pricing checkboxes from the list.

Formatting Tip: Remember to format your total Text Field as a Number or Currency under the Format tab to ensure it displays the final price correctly.

Solution 2

Control Radio Button Visibility via Mouse Up Actions

Set up conditional logic so that specific radio buttons only appear when a corresponding checkbox is selected.

Frequently Asked Questions

Why isn't my total field updating when I check a box?

Ensure that the calculation order is set correctly in your PDF form properties and that the export values of your checkboxes are formatted as numbers rather than text strings.

Can I hide multiple fields with one checkbox action?

Yes, you can use JavaScript in the Mouse Up action to change the display property of multiple field names simultaneously, or group them logically to hide the entire group.

Are PDF form calculations compatible across different PDF viewers?

Basic calculations and standard interactive actions are highly compatible with most major PDF readers, including Acrobat and WPS PDF, but they may not function properly in stripped-down browser-based PDF viewers.
