validate rule

Validate rules help you to ensure that users enter valid values in forms and that the system can process the information correctly.

A validate rule tests input values against conditions that you define as part of the rule. If the value does not meet the conditions, the system displays an error message when the user submits the form. For example, you can ensure that the customer provides their name and address before placing an order, or that the date of birth they provide is not in the future.
