Solution 1Recommended

Set Up Form Fields with Built-in Calculation

Add interactive fields, assign numeric export values to user choices, and configure a text field to automatically sum the total score.

To achieve automatic score totals, each selectable option (like a rating from 1 to 5) must be assigned a specific numeric value. A separate field is then designated to calculate the sum of these values.

1
Add Interactive Question Fields

Open your PDF form editor and insert Drop-down lists, Radio buttons, or Text fields for each question you want the user to rate.

2
Assign Numeric Export Values

Right-click each form field and select 'Properties'. Navigate to the 'Options' tab and set the 'Export Value' to the corresponding numeric rating (e.g., 1, 2, 3, 4, or 5) for each choice.

3
Insert a Total Field

Add a new Text field at the bottom of your document where you want the final score to appear. Name it clearly, such as 'Total_Score'.

4
Configure the Calculation Options

Right-click the Total field and open its 'Properties'. Go to the 'Calculate' tab.

5
Apply the Sum Function

Select the option 'Value is the sum (+) of the following fields'. Click the 'Pick' or 'Select' button, and check the boxes for all the question fields you want to include in the final total.

Set Up Form Fields with Built-in Calculation
Custom JavaScript Scoring: If your form requires complex math, such as weighted averages or conditional scoring, select 'Custom calculation script' in the Calculate tab instead of the basic sum function, and input the required JavaScript code.

Frequently Asked Questions

Why is my PDF form total not calculating automatically?

This usually happens if the export values for your choices (like radio buttons or drop-down lists) are not set to numeric digits, or if the calculation field is not configured correctly. Check the properties of each question field to ensure a numeric export value is assigned.

Can I use formulas other than addition for PDF calculations?

Yes. Most advanced PDF editors allow you to calculate the sum, product, average, minimum, or maximum of selected fields. For more complex math, you can use custom JavaScript in the calculation properties.

Will automatic score calculations work on mobile PDF readers?

Basic sum calculations often work on standard mobile PDF readers, but custom JavaScript calculations might not be fully supported across all mobile platforms. It is highly recommended to test your interactive form on multiple devices.
