    If you only want positive prices remove the comment markers "--" and make "AND MAX(Price) >= 0" part of the query.

    If you leave as is, you could potentially get a negative maximum value response from the query.

    E 12°55'05.25"

    Two minuses like this flags the rest of the line as a comment.

    Peso's solution is a perfect and extremely elegant solution to the problem as originally described - does it work for you?

    ah ha! that makes sense - never had to do a comment in sql - now i know (and knowing is half the battle - Gi Joooooooe)

    it does seem to work at first glance - i have to spend some time to verify it but i think it will do the trick.

    thanks very much to everyone!!
