[Koha] MARC Data Import Followup

Good evening all, Thanks to those who responded to my original question about inputting roughly 3,000 MARC records into Koha w/ the Staged Import Tool. I've followed the suggestions given to me, and produced a (what I thought to be) correct .mrk file. However, Koha sees only one record and that one has an error in it. Can someone spot the error, because my file checks out against the example I was given. Thanks, Zach Tucker IT Director, Nelson Memorial Library
