There are several Cookie Dough Fun cookbooks. I have 2 different ones. One I put the ISB in to post  it came up with the wrong cover. Now the books are not the same so why would it show the wrong cover with the right number put in, I tried both of the numbers on the one book. This would be misleading to someone as its not the book that is showing.

The cover does not have to match.  Some books have been through several releases and all have different covers.  The only things that need to match when you post a book are the ISBN, binding, title and author.  It's ok if the cover of your book does not match the one in the PBS system.

I know that but what Im saying is I have the book with the cover its showing and the recipes are not the same as in the one that I want to post

If that's the case Kay, you can get the right cover, upload it using the 'edit data' button and explain the current cover is not appropriate. The Data team will review your update and approve it if you make a good enough case.

That's what I always do when I find something that is not accurate.

I founf it thanks

Is the cover for a book completely different from what PBS says it is? Or is the whole book listing different?

If the image is just wrong to what the PBS listing says should be there, then an image correction should be submitted.

If the cover is just a newer/older/different edition of the same thing, usually image edit won't approve it because they aren't going to spend the time going back and forth if two members get into an upload-my-version war. 

If the whole listing is completely different, then its very possible the ISBN was reused and you would need to post your book as one without an ISBN.
