Calculating Form Fields

You can create calculated fields on a form. To do this, you only need to specify a calculation method for the given field. If you do this, the field value is automatically calculated when displaying the form. If the field is dependent on the value of one or more other fields, you can set which other fields in the form should automatically recalculate their value if they change. If the calculated field does not need to be recalculated when a form item changes, the form allows you to recalculate all the fields.
