VBS: Error message to appear when you hit Submit

Under the Family and Emergency Contacts page, we want Gender to be required only for specific relationship types. I created a validation rule, and the validation itself works as expected. However, the error message is displayed immediately when the user selects one of those relationships.

Is there a way to configure the validation or business rules so that the error message is displayed only when the user clicks Submit, rather than during data entry?

Here is a screenshot of my current validation rule.
