Good afternoon, I find that I'm unable to associate a vendor with a new or existing subscription record. Although I am able to search for a vendor on the subscription edit form at serials/subscription-add.pl, saving the form results in "The vendor does not exist." I'm using Koha 20.11.02. Perhaps I am missing something obvious. I'm doing this: * Navigate to Home > Serials, and click "New subscription" * On the form: o Search for and select an active vendor record and then a bib record o Click "Next" * Receive error, "The vendor does not exist." I've verified the following: * Vendor exists and is active * Bib record for the serial exists * Also, "claim serial issue" notice exists (this was the only acq/serial thing I found that was obviously undefined) I've tried creating a new vendor, and also using different bibs, and making sure their 008's indicate they are continuing resources, just in case. . I don't see anything useful in /var/log/koha except a bunch of errors like this that seem to be complaining about collection codes when I look at the problem line in the indicated script: [2021/05/28 14:44:33] [WARN] Use of uninitialized value in string comparison (cmp) at /usr/share/koha/intranet/cgi-bin/serials/subscription-bib-search.pl line 221. Is there anything else I might want to examine that could be causing the problem? Thanks for your time. Tasha R.
