Calc to show prior record in portal

Hi everyone,

In one of our portals we have a running list of books issued out (numbered). I'd like to create a 'not returned' letter for the prior book. Is there a way to do a calculation on this?

For example of the portal please see attached. The top record is the most recent issued book, the second is the prior. This will be a recurring thing so the calc must always look at the prior issued book even though there might be tons of prior records.

Hope that made sense! Thanks!

Create a relationship which includes T1::DateIssued > T2::DateIssued and sorts by DateIssued descending. Then T2::BookName refers to the 'prior' book.
