Surely a MySQL mailing list could have answered this? I thought they
had good community support.

Even MySQL doesn't accept that kind of thing!

You have doubled commas at several places in the VALUES list. I suppose
those are meant to be nulls - you should specify NULL instead of nothing
at all:

INSERT INTO form VALUES
('yes',NULL,'yes',NULL,'yes',NULL,'yes',...);

The way you have written it is bad practice any way. You should use
specific column names rather than relying on the current order in the
table:

INSERT INTO form (human_subj, animal_subj, toxic,...)
VALUES ('yes','yes','yes',...);

This will continue to work even if the table's column order changes for
some reason.
