Automation triggered by task complete and task body

[Santos, Luiz]

I'm struggling with setting up the automation to limit the search for a specific task.body only to the task that has been marked as complete.  For example, 

[ ] Task A 

[ ] Task AB

[X ] Task ABC

Here's what I currently have:

Trigger: When the task is completed

Condition: {{smart values}} condition to search for A once a task is completed, 

Result: It will come back with all three tasks, as all three "contain" the letter A (Task A, Task AB and Task ABC).

However, what I want is for the search to be limited to the task that has been marked as completed. For example:

[ ] Task A 

[X] Task AB

[ ] Task ABC

Condition: {{smart values}} condition to search for A once a task is completed, 

Result: Task AB

Can someone help me with this?

Thanks
