[QUOTE=chaley;4511328]I don't understand exactly what you want to do. It seems you want to do something with the series index when a book is added to the library, specifically copying the maximum series index for a series to a custom column for all books in that series.
If I am right then you can do what you want using the
Action chains plugin. You would add the new book(s), ensure their series information is correct, select the new book(s), then use an action chain that uses a python action to determine the highest series index for a selected book then copy that number to your "Total series" column in all the other books in the series.
Hi Chaley, that is exactly what I want to do, although it doesn't have to be at the time of adding a new book, I'd be happy to run a plug-in, or similar, every now and again to keep the information up-to-date.
Appreciate you pointing me towards Action Chains
