php - Mysqli bind param – number of variables doesn't match number of parameters

I can't understand why I get the error: "Number of
variables doesn't match number of parameters in prepared
statement".

My code looks like
this:

$DB['con'] = new
            mysqli($$DB['host'],$DB['user'],$DB['pass'],$DB['base']);

$stmt=$DB['con']->prepare("insert
            into
            points(iduser,puncte,nume,email,telefon,ultimulpost)values('?',?,'?','?','?',(SELECT
            CURDATE()))");

$stmt->bind_param('sisss',$idm,$mynumber,$nume,$email,$tel);
$stmt->execute();
