Hi there,
Thanks for the provided link, that didn't work in my case though...
Unfortunately I can't copy images to my messages, therefore my steps are attached in the file.
The issue was resolved in a very strange way. On the Student's cell Advanced Properties -> Items, I deleted 'pu_Student' and retyped it again exactrly the same way 'pu_Student', the same steps were done in the book cell Advanced Properties -> Items: deleted 'pu_BookCopy' and retyped it again in exactly the same way and all seems to work now.
As I'm spending so much time on resolving the issues due to the different versions on the tutorial and the on I'm working on, would it be possible to get extra learning time please?
Many thanks.
