- Scenario
- Filling or editing a PDF document that contains interactive form fields with mathematical calculation scripts.

Correct the Field Calculation Order in Acrobat
Adjusting the calculation order ensures that dependent formulas are processed in the correct sequence, preventing unexpected total changes.
PDF forms process calculations sequentially. If a total relies on a subtotal that hasn't been calculated yet, the final number will be incorrect. Fixing the order resolves this synchronization issue.
Open your PDF document in Acrobat. Navigate to the 'Tools' menu and select 'Prepare Form' or 'Edit Form' mode to access the interactive fields.
Look at the right-hand pane and click on 'More' (or 'Other Tasks' depending on your software version), then choose 'Set Field Calculation Order' from the dropdown menu.
A dialog box will appear listing all calculated fields. Select a field and use the 'Up' and 'Down' buttons to arrange them so that base values are calculated before the final totals. Click 'OK' to apply the changes.
