Script Validation methods
The single field script validation method enables you to 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 Properties of Single Field Script Validation window and the multi-field script validation method using the Properties of Multi-Field Script Validation window.
If you change the event type, the script sample also changes. Update your project or class script accordingly.
