Defining element validation logic

You can define validation logic for all input control elements.

If validation logic has been defined for an element, it is triggered when the user moves focus from the form element.

If the input control element contents are invalid, the field is highlighted in red and a warning message is displayed below it.

2. Click the VALIDATION tab in the configuration pane.

   

3. Select the Condition block modifier.

   • Url

6. [Optional] Click New validation to add another validation criterion to the logic block, and repeat step 5.
