               echo "<script type=\"text/javascript\">
               var cp_access_token = "xxxxx-xxxxx-xxxxx-xxxxx"; // ***** DON'T FORGET TO PUT YOUR ACCESS TOKEN HERE IN PLACE OF X's !!!! *****
               var cp_obj_1 = CraftyPostcodeCreate();
               cp_obj_1.set("access_token", cp_access_token);
               cp_obj_1.set("first_res_line", "----- please select your address ----");
               cp_obj_1.set("res_autoselect", "0");
               cp_obj_1.set("result_elem_id", "crafty_postcode_result_display_1");
               cp_obj_1.set("form", "address");
               cp_obj_1.set("elem_company" , "companyname"); // optional
               cp_obj_1.set("elem_street1" , "address1");
               cp_obj_1.set("elem_street2" , "address2");
               cp_obj_1.set("elem_street3" , "address3"); // or if you have only 2 address lines cp_obj_1.set("elem_street3" , "");

                  </ script>";
