It just says F at the bottom and won't output anything.

[MadTechie]

change

echo getGrades($average);

to

if(isset($_POST['grades'])){ echo getGrades($average); }

Awesome, that displayed the correct letter. Is there a way to also display the percent?

[mikesta707]

just display the $average variable
