Others have pointed out the possibility that $Table may be empty. I'd
like to add that I think there's another error -- as far as I know,
GROUP BY can only be used when you have aggregate functions such as SUM,
MAX, COUNT(...) etc. (For example, "SELECT custno, count(ordernum) FROM
orders GROUP BY custno ORDER BY 2 DESC" to select the customers together
with the number of orders, grouped by customer but sorted by number of
orders.)
Did you mean ORDER BY, perhaps?
Cheers,
Philip
