Script Validation Methods
These validation methods let you add more complex validations to your project.
You can also use the Multi-field Script Validation method to perform more complex invoice calculations to ensure that the total amount is correct.
Once added, you can configure the Single Field Script Validation method using the Single Field Script Validation Properties window and the multi-field script validation method using the Multi-Field Script Validation Properties window.
If you change the event type, the script sample also changes. Update
your project or class script accordingly.
