Hi Again, Still trying to get my head around Koha. So I've been through all the tags, identifying the ones our organisation is likely to use (mainly tradtitional koha items), disabling many others and now have a MARC form consisting of only 2 tabs, with tab 10 hidden. (Took me ages to figure out hiding was deliberate, or is it?) Quite a bit of work, but cool, now that it's done :-) Now that I have my fields, how do I control which field displays in the Opac? Also, changing the label to the field? They seem to be different in the Opac to the ones defined in the subfield screen. Seemingly this can this be somehow be done via the admin interface? Or have I misunderstood this and its all pretty much hard-coded? I read the somewhat cryptic help file in the Edit Subfields screen which refers to 17 different visibility condtions. An exclamtion mark (!) signifying where what is hidden. Does this actaully work? I've not yet been able to just take an obscure MARC field and deliberately make it display in the Opac... It would be absolutely awesome if this customisability was operational, so I hope I've just missed the main point (as I often do) and there is actually a way of achieving this. Best Regards to all, TIA Bo
