I've got a form that has a regular expression for a phone number.  Verifying that the phone number works just fine, but I've gotten some feedback about the error message that is thrown up.  

Is there a way to change the message "Value does not match designated pattern: \(d\d\d) \d\d\d-\d\d\d\d" or to hide it?

I can put (###) ###-#### in the Text Below Field which I think users will understand just fine.  However, I know I'm going to have end users confused by the '\(\d\d\d) \d\d\d-\d\d\d\d'.
