[KB] I always use array ref if I need to order a database data because
hash is unordered as you wrote and sort function sorts by key not by
vaue (At perl code, it also sorts by value) at template toolkit. I
tried to explain data structure Richard has trouble to Dave because
Dave wrote a solution
Richard,
I offer you using arrayref at template toolkit too. Template toolkit
supplies reaching values by table column names unlike perl code (t
Perl code, we ave to use index to reach array data) which is very
useful
