Look for up to 3 tasks that are complete

[Lawson02]

I want to build a scenario that looks at a project's tasks to see if they are complete. The project can have up to 3 specific tasks with set names that need to be completed. Is there a way I can accomplish this using custom fields while still using an instant webhook event? Like something along the lines of

Example pseudocode, I know there are some logic errors
If 1,2,3 or 1,2 or 1,3 or 2,3 or 1 or 2 or 3 = CPL ; true ; false

Hi @Lawson02 
You're asking to take action when in one project 3 child objects (tasks) have a certain condition. 

You'll need to create a project custom field for each of the 3 tasks and have a scenario that populates those fields whenever task completion (is this a task I'm interested in? yes > set custom field value on the project). Then you can create a calculated field that has the logic you describe. Or, you could create a checkbox field with a checkbox for each of the tasks and use Fusion to set those. 

Either way Fusion needs to set values on the project so you can create an event listener for projects.
