wpdb update

Everytime I try and use the wpdb update it never works but doesn’t throw any errors…

$wpdb->update("wpjb_job",
				  array('confidential' => $value),
				  array('id' => $this->getObject()->getId())					  );

this is the ‘error’ i get.. Image

and yes, those are the correct table names and everything.

I’ve even been able to use the same sql statement in phpmyadmin and it will execute perfectly.
