Hello, First of all, thanks for the helpful responses; I have a much better idea of how the advanced pattern tool works now. However, I tried entering the values suggested in the FAQ at http://koha.org/documentation/faq/how-do-i-create-a-new-subscription-for -a-journal-with-continuous-numbering/view, and they do not seem to be working. When I test the prediction, I get the following result: Based on the information entered, the Numbering Pattern will look like this: * Vol 104, No 486 * Vol 104, No 486 * Vol 104, No 486 * Vol 104, No 486 * Vol 104, No 486 If I remove the values from the "year" column (z), I get: Vol 104, No 486 Vol 104, No 487 Vol 104, No 488 Vol 104, No 489 Vol 104, No 490 Vol 104, No 491 Vol 104, No 492 Vol 104, No 493 Vol 104, No 494 Vol 104, No 495 Vol 104, No 496 Vol 104, No 497 The volume doesn't change every four. What I need is a prediction that looks like this: Vol 104, No 486 Vol 104, No 487 Vol 104, No 488 Vol 104, No 489 Vol 105, No 490 Vol 105, No 491 Vol 105, No 492 Vol 105, No 493 Vol 106, No 494 Vol 106, No 495 Is it possible that one of my other settings is affecting the prediction?
