pages in e-book

[Sarah]

Hi! :) I started reading this book http://www.goodreads.com/book/show/15... as an e-book, it has an ASIN (B0090V017C) instead of ISBN in its description, too, so I'm pretty sure that this is the ebook-version of it. There is no other edition to switch to, either. When I want to update my reading status, I can only update in pages, not in percent. Of course I don't know which page I'm on since I'm reading this as an e-book.
Is this some issue with the book or am I just too blind to find another updating-option, or should I add another edition?
Thanks! :)

When you go to enter an update and see "I'm on page ____ of 359"

Click on the word page, you will be able to switch to % which will correspond and allow you to enter what is on your reader.

Ah, okay. Then I guess it really was me being blind. :'D Sorry for bothering you with this and thanks for your help! :)

No worries, it isn't obvious that you can click on "page". If you run into it asking you % and you want to enter pages on a book.

When it says "I'm ___ % done" click on the % sign to switch to pages.
