Hi, I am trying to add values together in my while loop, so far I have: $q->query($DB, $SQL); while($avrating=$q->getrow()): $averageratings = $avrating['sum(rating)'] / $noofreviews; $overallaverage = round($averageratings, 2) + round($averageratings, 2); echo '<p>'.$avrating['rating_name'].': '.round($averageratings, 2).'</p>'; endwhile; echo 'x'.$overallaverage; $overallaverage += $overallaverage / 10; echo 'The Average: '.$overallaverage; from this, I get: x7.34The Average: 8.074 the total shold be: 42.34 then dived by 10 should be 4.23
