[Koha] How to hide Subfield in OPAC

[Eric Phetteplace]

Could you send a link to an example record? It's possible your URL is in an
unexpected format. I assumed that the text ".pdf" would appear somewhere in
the URL but if it does not, then the code will not work.

Best,

CCA is situated on the traditional unceded lands of the Ohlone peoples.
