you have the code inside a validatonb show if:
<?php
if (ValidatedField('cart','cart')) {
if ((strpos((",".ValidatedField("cart","cart").","), "," . "1" . ",") !== false || "1" == "")) {
if (!(false)) {
?>
<?php
if(isset($_POST['Coupon_Code'])) {
if(($_POST['Coupon_Code'] != "airflight") || ($_POST['Coupon_Code'] != "facebook") || ($_POST['Coupon_Code'] != "pinterest")) {
$_SESSION['badCoupon'] = "yes";
} else {
$_SESSION['badCoupon'] = "no";
}
}
?>
<?php if(isset($_SESSION['badCoupon']) && ($_SESSION['badCoupon'] == "yes")) echo "you entered an incorrect coupon code"; ?>
<span class="serverInvalidState" id="Coupon_Code_ServerError">Please enter valid coupon code</span>
<?php //WAFV_Conditional cart.php cart(1:)
}
}
}?>
it needs to be outside of the validation show if.
