It looks like you manually added those columns instead of using the Dreamweaver interface and that caused a few issues in your cart definition file: testeCart1_PHP.php.
Every time you see:
$itemWAUID, $itemBaffle, $itemBafflePriceInc
it should be:
$itemWAUID, $itemBaffle, $itemBafflePriceInc, $itemWAUID
a simple find and replace would probably fix it.
