Unable to list a giveaway

[Liwen]

Hi there! I'm trying to list a Goodreads giveaway for this book (Kindle version) and every time I enter the ASIN (which I copied from Amazon), I get this error: ASIN not found. Make sure you’ve entered the book’s ASIN correctly and that it’s uploaded and available for preorder or purchase in the Kindle Store (US marketplace).

What am I doing wrong? Please help! Thank you!
