CHE,
Your application can be opened for you to make the correction. Check your application for the email listing. If you can't find it your coordinator will send it to you. My DD's interviewing officer had to review her application before it could be submitted. Her coordinator just sent her the email contact. You have time, there will not be a lot of movement on the first few boards.
My application has not been submitted yet. I am submitting for the Oct. board.If the application is submitted, I would contact your recruiter/coordinator that is listed on the portal on the issue. Everyone I believe is assigned one.
