To ensure that you've correctly entered your email address, you must enter it a second time in this field.
To confirm the address, enter in the Retype Email field the same password you entered in the Email field.
When you click Next to move to the next page, a warning will display if your email addresses do not match. If so, retype them so that they match.
The Retype Email field is a "required" field. Information must be entered in the field in order for the page to be saved. If you fail to enter valid information in a required field, a popup error message is displayed when you click Next.
