Can't call method "bind_param" on an undefined value

The important information here is that $sth is undefined when you try to call bind_param on it. That happens when prepare fails. If you check prepare for errors, you'll get some more useful information: 

$sth = $dbh->prepare( $sql ) or die $dbh->errstr;

You can wrap that in an eval block if you want, too.
