Hi,
Is there a way to make two fields mutually exclusive? I would like for my journal articles to either show the URL or the DOI, but not both. In fact, if the DOI is present, I don’t want the URL to show at all.
I know you can make an element dependent on an other with a non breaking space, but can you do negative dependency? (If DOI is there, do not show URL)
Thanks for your help.
