The last line is my STDERR output. The previous line is an error message. The
trace() output seems to show rows() being set to '0' at line 70, which is "if
($sth->rows() == 0) {".
I don't understand perl says $sth->rows() isn't initialized, when it seems to
be set to zero, and why this system isn't working in this program, but seems
to work fine in my other one.
Thanks for any light you can shed on this problem.
My guess is that $_ is undef.
