Yep, I am an SQL newbie, but some help would be nice.
The script at the bottom terminates with this message:
  ANR2938E The column 'VOLUME_NAME' is not allowed in this context; it must
either be named in the GROUP BY clause or be nested within an aggregate
function.
and points to the left(volume_name, 8) portion of the query.  I have played
with it
and still get this message.  Could someone please explain why this is
occuring and
how I can fix my script?

TIA ... Jack
