## Set the Component Visibility Specify the logic that determines when the flow displays the component.
Option Description
When to Display Component

Configure when the component is displayed by using conditional logic.

You can set the components to:

Always
Always display the component.
When all conditions are met (AND)
Display the component when all of the conditions that you define are met. Define at least one condition.
When any condition is met (OR)
Display the component when at least one of the conditions that you define is met. Define at least one condition.
When custom conditional logic is met
Display the component when the condition logic that you define is met. Define at least one condition and specify condition logic.
## Validate Input Provide a formula that evaluates whether what the user entered is valid and the error message to display if invalid.
Option Description
Error Message Specify the error message that appears below the component if the user enters an invalid value.
Formula

Provide a formula expression that returns a Boolean value.

If the formula expression evaluates to true, the input is valid. If the formula expression evaluates to false, the error message appears below the component.

If the user leaves the field blank and the field isn’t required, the flow doesn’t perform the validation. If the user leaves the field blank and the field is required, the flow shows the default error message and not your custom error message.
## Specify the Behavior of Values on Revisited Screens Specify what this component does when a user enters a value, navigates to a previous screen, and then returns to the screen with this component.
Option Description
Use values from when the user last visited this screen The component retains the values that the user specified and doesn’t update the values to reflect changes made on previous screens.
Refresh inputs to incorporate changes elsewhere in the flow

The component updates the user-specified values to reflect changes made on previous screens.

If you pause and then resume the flow, the flow retains user-specified values only in Checkbox, Checkbox Group, Currency, Long Text Area, Multi-Select Picklist, Number, Password, Picklist, Radio Buttons, and Text components.
