PS

I've inserted the additional lines as above, but I get the following at the bottom of the report...

(Development version -- don't rely on the numbers on this report without double-checking them.
Change the 'Extra Notes' option to get rid of this message)

An error occurred when processing the template:

ERROR: Unbound variable: date->string
In current input:
  30: 53* (let* (#) (letrec # # # ...))
   ?: 54  (letrec # # # ...)
 307: 55* [display ...
 307: 56*  (date->string (current-date) "Printed at ~d/~m/~Y ~H:~M:~S")

…and I'm afraid the error messages don't mean a lot to me!
