I'm using NoteTabPro for EAD and it's been about 7 years since I had EAD experience. I'm trying to set up a finding aid to indicate C01 as series, c02 as subseries, c03 as a file. Right now my one finding aid on-line has only c01 series and c01 file with box and folder. The collection I have now is rather large and will have subseries. What must I do to get xml to parse correctly? I keep getting an error for C02 Element content is invalid according to the DTD/Schema. Expecting: head, abstract, container, dao, daogrp, langmaterial, materialspec, note, origination, physdesc, physloc, repository, unitda... which refers back to <dsc>. I searched the listserv archives but did not find coding help. I'm pretty much alone without any IT help. I only know html. Lauretta Scheller, Archivist MacMurray College Jacksonville, IL 217-479-7694
