Set the calculation order of form fields
When you define two or more calculations in a form, the order in which they are carried out is the order in which
you defined the calculations. In some cases, you may need to modify the calculation order to obtain correct results.
For example, if you wanted to use the result obtained from calculating two form fields to calculate the value of a third
form field, the first two form fields must be calculated together first to obtain the correct final results.
1 Choose Forms > Edit Fields > Set Field Calculation Order.
The Calculate Fields dialog box displays all calculable fields in your form and the order in which the calculations are
performed.
2 To change the field calculation order, select the field from the list, and then click the Up or Down button as needed.
Acrobat automatically performs all assigned field calculations when you are creating and testing your form fields.
For convenience while you work, you can turn off automatic calculation in the forms preferences.
Signed tab for form field properties
The Signed tab is available only in the Digital Signature Properties dialog box. Selections made here determine what
happens when the user applies a digital signature to the form.
Nothing Happens When Signed This is the default.

• All Fields Prevents any changes to any form field.
