Okay, folks, here's another one:  

I'm looking to create an email notification when Prospect_Status__c changes from one of two particular values to any other value (or to blank).  When those either of those two particular values are present, a checkbox is automatically checked, and this is the basis for the email notification: when it goes from checked to unchecked (i.e., from either of the two particular values to a different or no value).  However, when a record is created, it may or may not have a value in this field.  The evaluation criteria in a workflow rule are 1) when record is created, 2) created, and every time it's edited, and 3) created, and any time it's edited to subsequently meet criteria - I want to eliminate the created part to avoid getting a notification every time a record without a value in this field is created.  Suggetions?  

Thank you!
