Hello Brian,

If you want to add the values in a number of columns:

create a query like this
$ch == 'n'
$ch == 'u'
($ch != 'n') && ($ch != 'u')


select sum(IF(ch='n',1,0))
notrecognisedcount,
sum(IF(ch='u',1,0))
discontinuedcount,
(count(1)-sum(IF(ch='n',1,0))-sum(IF(ch='y',1,0))) validorderscount
from table

This type of query may give you what you are looking for directly without
having to loop through
each record and go though lots of external logic to get your info from the
database.

If I understood the tables that you are working with then it would be an
easy matter of using writing a better query.

I hope that this helps.
