[Koha] How to make MARC Fields Appear in Opac?

[Bo Schafers]

Hi ,

Just wondered if anyone had any pointers to this topic posted a few days 
ago. I have tried -via the subfields screens- to use the 17 visibility 
setting mentioned in the help file but have not been able to make tags 
apear...

Here's a small, specifically related example. In my Koha installation I 
have defined:

For Marc: 942K  Dewy/Call Number
For Items: 952K  Call Number (Combined)

These display fine throughout various screens on the intranet but how 
can I make the call number show in the opac? Which subfield/linkage is 
required for the opac field to display 942/952 fields. Go to 
http://opac.bswa.org/cgi-bin/koha/opac-detail.pl?bib=3  - the call 
number area is not filled here. If you go into MARC view you can see the 
call number.

Any help would be much appreciated.
