Also, I fixed the "S" in the following to "LBS" as described in another post. Didn't know if that had anything to do with it. Is there a way to fix that permanatly so I don't have to edit it each time I use the checkout wizard.
$Shipping_PackageArray[$Shipping_PackageIndex]["WeightUnits"] = "".strtoupper($eCart1->WeightUnits)."LBS" ."";
