Hey,
Try adding quotes ' ' or " ". Interesting that the others work without the quotes, as far as I am aware, that's php structure.
$label=$_POST['rulelabel'];
$description=$_POST['ruledescription'];
$course_1=$_POST['course'];
$prerequsite_1=$_POST['prerequsite'];
$errormsg=$_POST['errormessage'];
You can use the php line to test the output.
echo $description;
P.S You might not want to publicly post passwords again. :)
