How to Display Text Based on a Score Range in an Acrobat PDF Form
Question details
The user needs to calculate a total score from radio-button selections and automatically display a corresponding text category (such as risk levels) in a separate text field.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Building an interactive PDF form where a numerical score automatically determines and displays a categorical text outcome based on defined value brackets.
- Observed behavior
- The form setup requires assigning numeric export values to radio buttons, calculating the total sum in a designated field, and using a custom JavaScript calculation to output specific text depending on the score.
Ensure you are using a PDF editor that supports advanced form authoring and custom JavaScript calculations, such as Adobe Acrobat Pro.
Use Custom Calculation Scripts in Acrobat
By combining the standard Sum function with a custom JavaScript calculation, you can automatically convert numerical scores into specific text categories.
This solution relies on three components: setting explicit export values for your input buttons, summing those values into a hidden or visible score field, and then reading that score field via a custom script to populate the final text field.
Right-click each of your radio buttons and go to Properties. Under the Options tab, set the 'Export Value' to the specific numeric value needed for the final score.
Create a new text field named 'RiskLevelScore'. Open its Properties, navigate to the Calculate tab, select 'Value is the sum (+)', and choose the radio buttons you want to include in the calculation.
Create the final text field where the text category will appear (e.g., 'RiskLevel'). Open its Properties, go to the Calculate tab, select 'Custom calculation script', and click the Edit button.
In the JavaScript editor, enter the following code to evaluate the score: var nScore = this.getField("RiskLevelScore").value; if (nScore >= 15) event.value = "High Risk"; else if (nScore >= 3) event.value = "Moderate Risk"; else if (nScore >= 1) event.value = "Low Risk"; else event.value = "No Risk"; Click OK and close the properties panel to save your changes.

Frequently Asked Questions
Why is my PDF form calculation script not updating automatically?
This is usually caused by an incorrect calculation order. Acrobat calculates fields in a specific sequence. Go to 'Prepare Form' > 'More' > 'Clear Form', then check the 'Calculation Order' to ensure the 'RiskLevelScore' field calculates before the custom text script evaluates the score.
Can I use this script for other text categories like letter grades?
Yes. You can modify the script variables and range conditions to output any text string. For example, you can adjust the numerical thresholds to output grades (e.g., 'A', 'B', 'C') based on test percentage scores.
Will this JavaScript work on mobile PDF viewers?
Complex custom JavaScript in PDF forms is widely supported on desktop PDF applications like Adobe Acrobat or WPS Office PC versions. However, third-party mobile PDF readers or built-in browser viewers often strip out or ignore JavaScript, meaning the automatic text calculation might not function correctly on mobile devices.
