In order for the Submit Review button to work, your book review must be approved and live. To verify this on Amazon in particular, you can normally check your Amazon profile page, as all of your reviews should show up on your profile. However, in some cases a book review does NOT appear on your profile, and that is generally due to one of two reasons:

1. Your review isn’t approved yet.  Amazon sometimes posts reviews immediately, and other times they spend time approving them – sometimes many days!  If your review isn’t approved, it not only won’t show up on your profile page but it doesn’t show up under the book either. In this case, there is no way to add your review link to our form, because your public review link doesn’t yet exist.  You may be able to see it on your end, but that’s a private edit only link that no one else can view.  In these cases, all you can do is wait for Amazon to approve the review before asking us to look for it.
2. Your sensitivity filter is preventing a review from showing up on your profile.  Amazon has a filter which determines whether certain reviews will show up on your profile.  You can change those settings here. In this case, your review is posted but it cannot be seen on your profile (although can still be seen on the book’s product page). Note that we should still be able to find your review even if your filter is active, but it makes it harder for you to tell if it’s live or not.
