The memo field on this tab allows you to enter a script to define inclusions and exclusions. In such a script, you can record in which instances a feature is valid or invalid, for example:

• A 4WD car is only available in blue ('Blue' is the only valid option).
• For a British customer, the driving side must be 'Right', and the 'Left' option will be invalid.

A validity script allows you to determine which options will be visible and/or can be answered during the configuration.

Example

ValidIf = AnswerToQuestion ("COLOR") = "GREEN"
