1) When I create a new contact on an account and a field has a certain value, a checkbox on the new contact is automatically checked. If that is checked I need to force the user to fill another field.
2) I have a validation rule in place that is working for already created records when they are edited and that particular field is checked and the field I need to require is blank that is working.
How do I ensure that the user fills in the field on a new record. I don't want them to be able to save without filling in the field.
