Adding values from several subtasks and populating total in parent

[Rich Nuzzi]

Basically, I have a field in several subtasks. The field is called "Failure". I want to total up all of the numbers in the subtask "Failure" fields (there are 6 subtasks) and put the total in the parent field called "Total Failures" using automations.

Any help is greatly appreciated. Thank you.

Hello @Rich Nuzzi 

You could do that with an Automation Rule.
