Thank you for the reply Cara.
But as I indicated, when I click on Seller Details or Manage seller Details, I have a profile listed but when I click --> Edit I only get a blank page with no existing details to work with or edit.
Say, I found it... I had to click NEXT on 3 or 4 blank screens and finally came to a "Terms of Sale" screen where all my existing content was. Very confusing.
