I am finding it very hard to talk to someone about this ongoing problem. I am having trouble printing a batch (class) list. I work at a school. The older 2 classes are fine, so something must have changed to Koha whilst adding the newer students that prevents me from printing off a barcode list.
Hi Jo, can you please bring up your problem on the mailing list? Bugzilla is for reporting bugs and enhancement wishes but very few people read all the interactions here. Also: 3.22 is on longer supported and won't receive any bugfixes. But if you haven't updated, the issue is probably something else. Please include the steps on how you print a batch list - it's not clear to me which functionality in Koha you use for this, so hard to see where the problem is. How did you add the students? Manually or did you import them? What information doe you need on the list and where is it stored in the patron record?
There is not enough information here to figure out the problem the reporter had - marking INVALID.
