Division by zero
I get this error
Warning: Division by zero in /home/sites//public_html/mini.php on line 155
Line 155 is
$percent = round((($rankp-$old)/($max-$old))*100);

One, some or all of your variables does not have a value.

($max - $old) * 100 = 0. You can't divide by 0; it is a mathematical impossibility.

You can check to see if ($max - $old) * 100 is equal to zero prior to dividing by it.

Actually just check to see if $max-$old equal 0 before you divide by it since the * 100 is outside of the parentheses.
