I have followed the 'Common composite custom columns' instructions in this thread:
https://www.mobileread.com/forums/sho...ry+view+lookup
The column type drop down does not have the option 'Column built from other columns'. The 'Lookup name' is just a text box - where do I chose templates from?
I also have no data listed in ISBN or format columns in library view.
