I added thse two tags to the sql, and now I get same error but at line 998

$id_map['products'][(string)$product_data->id[0]->data()] = $nid;

Fatal error: Call to a member function data() on a non-object in /var/www/vhosts/vlfit.com/httpdocs/sites/all/modules/contrib/ubercart/uc_importer/uc_importer.module on line 998

What does this line do and does this have something to do with more xml tags missing. Here is updated xml file

Thanks
Jim
