Updating due date of epic from child issues

[Mark G]

I want the epics due date to be the due date of the last issue in the epic. is there an easy way to accomplish this? here's one that I'm using to update story points and due date at the same time just to debug my logic..... 

even when I set a hard date for the due date it doesnt update when I run the rule but the story points is updating fine and the log says sucess...
