Error itms-9000 "could not parse OPS/glossary.xhtml"

Question

Has anyone received this error message when trying to deliver an ibook through iTunes Producer?
ERROR ITMS-9000 "could not parse OPS/glossary.xhtml: duplicate id: p2" at Book (MZItmspBookPackage)"
I can't translate that, the ibookstore people are VERY (5 days) slow in responding, and my book can't go through until I've "fixed" the problem.  Glossary links are intact, intro movie is in a separate place (not glossary), and I'm at a loss!!

Answer 1

Edgar,
My solution came as a suggestion from my computer guru son.  Delete every item in the glossary.  Since that wasn't practical, I copied each item completely and pasted it to Notepad.  THEN deleted each item.  In re-inputting the items (copied from Notepad), I used the iBooks "glossary creator" to create each item.  Apparently, as I was "creating my own" glossary items, iBooks was creating each item in the background, so duplicates were being created.  Once I input the glossary items ONLY through the iBooks "glossary creator" system, there were no duplicates and the submission process went through instantly (took a while, because of the size of the book).  About your videos in the glossary, try abridging the video (if it was a duplicate of something used somewhere else in the book) and renaming it a different name, THEN include it in the glossary.  It may be thinking that the video is duplicated in the glossary because it's being used elsewhere.  If the two (or three) videos all have different names, I think they would pass.
Another thing that caused problems in the book was in dealing with .pdf files.  DON'T USE .PDFs.  Re-type the verbiage.  Including .pdfs created its own set of problems!
Good Luck!!
