ThreePess Validation gives me this error message: ERROR: The Voyagers Series_8.epub/OEBPS/content.opf(8): Entity 'apos' is undeclared
Does anyone know what this means and how I can fix it? :)

Maybe someone can look at it. I just can't get it to validate. Thanks

Sounds like you have html entities in your opf file. That's not allowed. Look for instances of ' in your opf file and replace it with the actual apostrophe (’) character.

Thank you so very much!!!!!!!!!!!

No problem. :)

If you are real then I am blessed:)

I found it and now it VALIDATES!!!!!!!!!!!! Thank you! DiapDealer! You were right!
