Usage of a variable attribute

1

Is it possible to use a variable in a variable for attribute m1 as part of a sensor?
I want to use the states part as part of a notification and set the m1 attribute name within variables

"{{ states['sensor.melding'].attributes.m1 }}"

not working line 4
{% set another = 'm1' %}
{{ another }}
works {{states['sensor.melding'].attributes.m1}}
not working {{states['sensor.melding'].attributes.'{{another}}'}}

found it !
more of a lucky shot!

{% set another = 'm1' %}
{{ another }}
{{ states['sensor.melding'].attributes[another] }}


and this is a part of where it all comes together
alias: visite
icon: mdi:party-popper
variables:
  berichtid: m5
  keuze: "{{ keuze if keuze is defined else states('input_boolean.visite') }}"
  mode: "{{ iif(keuze == 'on', 'off', 'on') }}"
  avond: "{{ states('input_boolean.scene_avond') }}"
  dagtype: "{{ dagtype if dagtype is defined else states('input_select.dagtypen') }}"
  actiontrigger: "{{ actiontrigger if actiontrigger is defined else 'niet gespecificeerd' }}"
  actionstate: "{{ actionstate if actionstate is defined else 'niet gespecificeerd' }}"
sequence:
  - service: variable.update_sensor
    data:
      replace_attributes: false
      attributes:
        '{{berichtid}}': test7m5
    target:
      entity_id: sensor.melding
    enabled: true
  - service: script.turn_on
    data:
      variables:
        bericht_id: "{{ states['sensor.melding'].attributes[berichtid] }}"
        bericht_logtype: debug
        bericht_titel: xvisite (script)
        bericht_inhoud:
          keuze: "{{keuze}}"

          dagtype: "{{dagtype}}"
          actiontrigger: "{{actiontrigger}}"
          actionstate: "{{actionstate}}"
    target:
