Send Email on Return Authorization Approval

I'm trying to do a simple workflow to send an email whenever a Customer Return Authorization is approved, but I can't seem to get it work.  Here's what I have:

Workflow Basic Info:  Record Type:  Transaction
                                 Sub Type:  Return Authorization
Event Based Initiation
Trigger Type:  Before Record Submit
Condition of Status=Return Authorization: Pending Approval

I then have a Single State with 1 Action to Send Email
Trigger Type:  After Record Submit
Status = Return Authorization:  Pending Receipt or Pending Refund

I don't want the email sent when the items are received, and we have some return authorization that have Non Inventory Items on them, which is why I added the status of Pending Refund as after the Return is Approved, it changes directly to Pending Refund.
