Help with condition template

Configuration

Hi,

I need some help with this condition template. I need it to return when { task_old.task_title == ‘task’}.

- id: '5166189215216854'      
  alias: DALS vacuum bedroom done
  description: ''
  trigger:
  - entity_id: sensor.gtasks_dagpass
    platform: state
  condition:
    condition: template
    value_template: >
        {% for task_old in trigger.from_state.attributes['tasks'] %}
          {% if task_old not in trigger.to_state.attributes['tasks'] %}
            { task_old.task_title == 'task'}
          {% endif %}
        {% endfor %}
  action:
  - service: notify.pushbullet
    data_template:
      message: >
        {% for task_old in trigger.from_state.attributes['tasks'] %}
          {% if task_old not in trigger.to_state.attributes['tasks'] %}
            {{ task_old.task_title }}
          {% endif %}
        {% endfor %}

At the very least:

{{ task_old.task_title == 'task' }}
