[PHP] math - somethings wrong

[Michael Roark]

$percentage=(($target_score/($fleet_score+$total_score))*.4)*100;
 if ($percentage >= 10) {
                $percentage='10';
                $capped=$target_roids*($percentage/100);
        } else {

                $capped=$target_roids*($percentage/100);

        }
}


I get different results on a calculator than I don with this script. This is the order 
i do things on the calc:

($fleet_score+$total_score))*.4)

then the 

(($target_score/

then the 

*100

i think my problem is some where in the if ($percent >=10) that port is there because 
regardless of the results returned by the formula the percentage can never be larger 
than 10
