Perhaps a wise monk can enlighten me but this MySQL error is boggling my mind. How can I get an undefined value on bind_columns() if my variables are set prior to the bind? I never had this error before. 
Can't call method "bind_columns" on an undefined value at manage.pl li
+ne 73.

My code (with line numbers) is here 
000068:    my $data = qq(SELECT catname, path, root FROM categories WH
+ERE root = "1" ORDER BY catname ASC);
000069:    my $sth = $dbh->prepare($data);
000070:    $sth->execute() or die $dbh->errstr;
000071:      
000072:    my ($catname, $path, $root);
000073:    my $sth->bind_columns(\$catname, \$path, \$root);
000074:
000075:    while($sth->fetch)
000076:    {
000077:       print qq~
000078:       <a href="manage.pl?process=categories&path=$path">$catna
+me</a><br>
000079:       ~;
000080:    }

Can anyone see what might be going wrong?
