Dear All, Springer has provided me with a .bin file. This file has marc21 data in it and when I stage it into Koha it works fine. However I have to modify this marc file and add fields or edit fields using the [MarcEditor] tool. Now the problem is, in order to read it correctly INSIDE the MARCEDITOR, i change the extension from .BIN to .MRC This is ok up to the loading of the data into the MARC Editor. Now, I added some new fields as well as I have edited some fields. Now the issue is here. ------------ After adding/editing fields in this file, I SAVE as MRC. When I try to load this NEW marc file into KOHA using Staging, it does not go through and it says NaN error. I am not sure what to do now. I am using Koha 3.0. I forgot to add an example of the first-file data[the .bin] file from Springer and the data after I convert using MarcEditor and Koha can't read it. ========BEGINNING ====Works======= 02417cam 2200577Ia 4500001001300000003000600013005001700019006001900036007000700055008004100062040003600103020001800139020001500157029002200172029001800194029002200212035002100234037006100255050002500316060001500341060002400356072001300380082001800393049000900411100004800420245020700468260003400675300007400709533024300783504005101026650002501077650002801102650002101130650003001151650002801181650003901209650001901248650004001267650002401307650002401331650002801355650001701383655002901400700002201429776007601451710003401527856014301561856008101704938004001785994001401825 ocn184903927 OCoLC 20100416100144.0 m d cr cn| 071219s2007 nyuacf sb 001 0 eng d aGW5XE cGW5XE dGW5XE dYDXCP dTEX a9780387465265 a038746526X 1 aAU@ b000042133518 1 aNZ1 b11675905 1 aAU@b000043253015 a(OCoLC)184903927 a978-0-387-28223-7 bSpringer nhttp:// www.springerlink.com 14 aQP368.7 b.K37 2007eb 14 a2006 N-753 14 aWL 102.8 bK18e 2007 7 aQP 2lcco 04 a612.8/042 222 aMSDA 1 aKarczmar, A.
