订票回放失败，事物3_select一直不过，求助懂的朋友

  lr_start_transaction("3_select");

    web_submit_form("reservations.pl_2",
        "Snapshot=t8.inf",
        ITEMDATA,
        "Name=outboundFlight", "Value=242;193;09/22/2016", ENDITEM,
        "Name=reserveFlights.x", "Value=54", ENDITEM,
        "Name=reserveFlights.y", "Value=10", ENDITEM,
        LAST);

    lr_end_transaction("3_select",LR_AUTO);
