When there are multiple calculations in a form, they are performed in the order you defined, and sometimes it takes a specific order to get correct results.

For instance, in order to use the result obtained from calculating form field A and B to calculate the value of a third form field C, A and B must be calculated together first to get the correct final results.

  1. Choose Form > Set Field Calculation Order to open the Calculate Fields dialog box, which displays all calculable fields in your form and the order in which the calculations are carried out.

  2. To modify the field calculation order, select the field from the list, and then click the Up or Down arrow button

  3. Click OK.

Note: when you create or test form fields, Right PDF will automatically perform all calculations. You can go to Preferences > Forms and deselect Automatically calculate field values to disable this.
