It looks like you had hand edited line 217 but made a mistake.
That line should be:
$WA_fieldValuesStr = "".((isset($_POST["Product_Name"]))?$_POST["Product_Name"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Product_Number"]))?$_POST["Product_Number"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Schofield_Stone"]))?$_POST["Schofield_Stone"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Stone_Center"]))?$_POST["Stone_Center"]:"") ."" . $WA_AB_Split . "".((isset($_POST["3North"]))?$_POST["3North"]:"") ."" . $WA_AB_Split . "".((isset($_POST["bridgewater"]))?$_POST["bridgewater"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Location_ID1"]))?$_POST["Location_ID1"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Location_ID2"]))?$_POST["Location_ID2"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Location_ID3"]))?$_POST["Location_ID3"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Location_Codes"]))?$_POST["Location_Codes"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Category_ID"]))?$_POST["Category_ID"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Description"]))?$_POST["Description"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Color"]))?$_POST["Color"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Sizes"]))?$_POST["Sizes"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Sold_by"]))?$_POST["Sold_by"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Small_pic_Name"]))?$_POST["Small_pic_Name"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Big_Pic_Name"]))?$_POST["Big_Pic_Name"]:"") ."" . $WA_AB_Split . "".((isset($_POST["Spec_PDF_Name"]))?$_POST["Spec_PDF_Name"]:"") ."";
you were missing the $WA_AB_Split line between the bridgewater and Location_ID1 fields in your code.
