The Value Validation properties determine the validation of values entered into the text field. These properties can be used to ensure that the information entered into forms fits within specific parameters:
•Validation determines how values are validated:
•Value in Range sets the range within which values entered into the text field must fall:
•From specifies the minimum value.
•To specifies the maximum value.
The Value Calculation properties determine the value of text fields from other text fields, and are used in forms where entered form data creates the value of further forms, such as when several orders are placed that combine to give a total cost. The available properties are detailed below:
•None specifies that calculations are not performed.
•Sum uses the sum of specified fields.
•Product uses the product of specified fields.
•Average uses the average of specified fields.
•Minimum uses the minimum value of all the specified fields.
•Maximum uses the maximum value of all specified fields.
•Please note that when the Sum, Product, Average, Minimum and Maximum properties are used, the additional entry "Fields" will appear beneath the Calculation property. Use this entry to specify the fields used in these calculations.
•Simplified Notation enables the insertion of a custom calculation to be performed on fields. Use the Simple Notation box to determine the calculation. Use the document field names and standard mathematical notation (+, -, *, /) to specify the calculation. If there are spaces in form field names then they must be entered in quotation marks. For example: Field1 + Field 2 / "Division Field" * 64.
The following example details a simple value validation of values entered into the text field 'Text1':
