MJ & Paul: Thanks for your suggestions! I now have Koha about 90% up and running. The OPAC works OK (including search), and many of the Intranet functions work OK - Our data is there, and we have MARC tags! The remaining problem is that the MARC search does not work - it takes me to a white error page. The MARC search categories are there, it just doesn't do the search. I assume this has something to do with MARC configuration. I checked the Koha error log, and found this: Can't use an undefined value as a HASH reference at /usr/local/koha/intranet/modules/C4/SearchMarc.pm line 116. [Thu Jul 1 11:00:04 2004] [error] [client 192.168.0.5] Premature end of script headers: /usr/local/koha/intranet/cgi-bin/search.marc/search.pl Does this ring any bells? Is there something I am obviously not doing? How do I define the value for the HASH reference? Robert
