Hi Steve,

Glad to hear you got your solution; however, based on your description, I
thought that the phone number field is a required field. By just setting the
Validation Rule to Is Not Null, you might check if the user can skip that
field and not enter anything to see if the Validation Rule will still kick in.

Good luck with your project.
