2 Bugs

I found 2 really bad bugs in your plugin I had to fix in order to make it work !

in result.php, on line 62, your system compare strings with <= here is my fix :

$points = floatval($points);
foreach($results as $result) {
  if(floatval($result->points_bottom) <= $points 
     and $points <= floatval($result->points_top)) 
         return $result;
}

in quizzes.php on line 193, you cast the value into an int and it should be a float :

$points += floatval($_POST[‘points’]);
