Converting a book from InDesign CS4. When running through a validation program I keep getting the following error message:

ERROR: 101_SupposeItIsBS.epub/OEBPS/content.opf(2): date value '' is not valid. The date must be in the form YYYY, YYYY-MM or YYYY-MM-DD (e.g., "1993", "1993-05", or "1993-05-01"). See http://www.w3.org/TR/NOTE-datetime.

I understand the message, but can't find the location of the problem. I have gone through the "File Info" information in InDesign and made sure that all of the dates are in the right format. Still get the message.

Any ideas?
