Hello all, I downloaded and installed Koha 2.0.0RC1 today. This is the first time I have tried Koha. I believe it is working correctly, however the only thing I did was to try to add two members. I aheven't even tried to add a an item. The members added fine, however when I tried to update the two members, I received an error. The error says: The following fields have a forbidden value. Please push the back button and try again : Invalid_cardnumber I did not change the member number when I created the two users. I took the default number. Is this a bug or did I do something incorrectly? I noticed on the test drive version that Koha also complained about the card number when I tried to edit the patron I created. I'm not sure if it makes a difference, but I am running Koha on Mandrake 9.2 using Apache 2. Thank you, Edward Corrado UNIX Admin/Library Systems Manager
