What must be selected for the Execute if false script block to run in a UI Policy?

For the Execute if false script block within a UI Policy to run, it’s necessary to select the option that specifies the conditions under which the script should be executed when the specified condition is not met. The choice to select "Reverse if false" is designed specifically for handling situations where the initial condition evaluates to false.

When this option is chosen, the application knows to execute the script block that manages the scenario when the condition does not hold true. This allows developers to implement functionalities that apply when certain criteria are not present, such as resetting fields, changing the visibility of form components, or clearing values.

By correctly using this option, the developer can ensure that specific actions are taken when the conditions outlined in the UI Policy are not satisfied, thereby enhancing the dynamic behavior of the user interface in ServiceNow applications.
