Hello, I have on installed Koha 3.00.02.012 on a test/training server. My current task is to export test patrons from our existing Millennium system into Koha. I created a program using c# to generate a csv file into the appropriate format for import into Koha. Looking at the output file, it seems to me that the format is how Koha wants it. Unfortunately, I get many errors upon import: # Line 2 Critical field "surname" missing (borrowernumber: UNDEF; surname: UNDEF).

All of these "patrons" aren't real people, in case anyone was wondering :-). I've attached my output.csv file. Does anyone know what I am doing wrong? Let me know if there's any additional information that would help. Thanks!! Stephanie Nordmann System Administration Manager St Louis County Library www.slcl.org <http://www.slcl.org/>
