How to Fix Acrobat JavaScript Commission Formula for a Sales Range
Question details
The user needs to correct a custom JavaScript formula in an Acrobat PDF form to calculate a 15% commission rate only when total net sales fall precisely between $50,000 and $80,000.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Setting up a dynamic commission calculation inside a fillable PDF form that depends on a specific numerical sales range.
- Observed behavior
- The original script fails to calculate correctly because it contains an invalid variable name with spaces and an improperly constructed mathematical range condition.
Verify the exact field names used in your PDF form before updating the script, as JavaScript references are highly sensitive to typos and case variations.
Correct Variable Names and Apply the Logical AND Operator
Fix syntax errors by removing spaces from variable names and utilizing the logical AND (&&) operator to properly test both ends of the numeric sales range.
JavaScript engine requirements forbid the use of spaces in variable declarations. Using underscores (e.g., Total_NDR) or camelCase ensures the system parses the data correctly. Furthermore, range conditions require evaluating both the minimum and maximum boundaries simultaneously using '&&' rather than a continuous algebraic expression.
Change variables like 'Total NDR' to 'TotalNDR' or 'Total_NDR' so they do not contain spaces.
Open your PDF form in edit mode, right-click the target commission field, select 'Properties', and navigate to the 'Calculate' tab.
Select 'Custom calculation script' and declare your numeric fields using the Number() function, such as: var TNS = Number(this.getField("TNS").valueAsString);
Input the corrected logic to multiply the value by 15% if true, and return 0 if false: if (TNS >= 50000 && TNS <= 80000) { event.value = TotalNDR * 0.15; } else { event.value = 0; }

Frequently Asked Questions
Why does my Acrobat JavaScript calculation return nothing?
Blank returns usually happen due to syntax errors in your script, such as using spaces in variable names, missing brackets, or referencing a field name that does not exist exactly as typed.
How do I test a numeric range correctly in PDF JavaScript?
You must use the logical AND (&&) operator to test both conditions. For example, instead of writing '50 < x < 80', you must write 'if (x > 50 && x < 80)'.
How can I view errors for my PDF form scripts?
You can open the built-in Acrobat JavaScript console by pressing Ctrl+J on Windows. This debugger console will display error messages generated when the script attempts to run.
