Structure for dissector plugin

I have a custom header as {version[2 bits], control[8 bits], high[6 bits], low[11 bits], index[5 bits]}

I am trying to create the data structure for my dissector plugin and I am having trouble with it.

Currently my structure looks like this:

      { &hf_packet_skip1,
          { "PACKET SKIP1", "packet.skip1",
          FT_UINT16, BASE_DEC,
          NULL, 0x0,
          NULL, HFILL }
      },
      { &hf_packet_version,
          { "PACKET VERSION", "packet.skip1.version",
          FT_UINT16, BASE_DEC,
          NULL, 0x0,
          NULL, HFILL }
      },    
      { &hf_packet_control,
          { "PACKET CONTROL", "packet.skip1.control",
          FT_UINT16, BASE_DEC,
          NULL, 0x0,
          NULL, HFILL }
      },
      { &hf_packet_high,
          { "PACKET HIGH", "packet.skip1.high",
          FT_UINT16, BASE_DEC,
          NULL, 0x0,
          NULL, HFILL }
      },
      { &hf_packet_skip2,
          { "PACKET SKIP2", "packet.skip2",
          FT_UINT16, BASE_DEC,
          NULL, 0x0,
          NULL, HFILL }
      }
      { &hf_packet_low,
          { "PACKET LOW", "packet.skip2.low",
          FT_UINT16, BASE_DEC,
          NULL, 0x0,
          NULL, HFILL }
      }
      { &hf_packet_index,
          { "PACKET INDEX", "packet.skip2.index",
          FT_UINT16, BASE_DEC,
          NULL, 0x0,
          NULL, HFILL }
      }

Please help me get the correct structure.
