That can't be true. If the above code said it was NULL, then the
second IF block below can't be executing. Are you sure that there
isn't something in between these two blocks of code. Is this even
your "real" code, or just a quick rewrite.

I execute this code:
-------
$new_price = 49;
if (is_null($_SESSION['nomex'])){
echo " is null.";
}
else {
echo " is not null.";
}
if ($_SESSION['nomex'] != "^^no^^"){
if (!is_null($_SESSION['nomex'])){
// NOMEX Lining
$new_price = $new_price + 100;
}
}
echo "$".$new_price;
-------

Output is:

is null.$49
