Note: Field names are case-sensitive.
Custom Calculation Script Displays any custom scripts you have added for calculations. The Edit button opens a dialog

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 > Tasks > Other Tasks > 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.

Mark As Read-Only Prevents further changes to the digitally signed form, according to the selection in the pop-up menu:
• All Fields Prevents any changes to any form field.
• All Fields Except These Allows changes only to the form fields you select by clicking the Pick button and selecting
check boxes for the fields that you want the user to be able to edit after signing.
• Just These Fields Prevents changes in only the form fields you pick.
This Script Executes When Field Is Signed Activates a custom JavaScript when the user digitally signs the form. Use the
