On Edit ->On Validate section in Deluge is used to write the Form validation scripts when a record is edited. You can check for field values and tell the user to enter the right value. This part is executed after user clicks on the Update button and before updating the record to the database.
See https://creator.zoho.com/sampleapps/script-actions/#View:On_Validate_View , click on Edit next to any record and give different email addresses for the fields you see there and click on Submit.
For example, while editing a record, if you want to confirm a user’s email address using two fields Enter your Email and Confirm your Email and give an error if emails do not match, you can use the On Edit ->On Validate script section.
After you click on Submit (with different data for emails), you will see the message as “Invalid Entries Found” and “Email Addresses do not match“.
