I can't get a Workflow Alert to work.

I can't get a Workflow Alert to work.

I'm trying to make a workflow rule that alerts me when an assigned task is overdue.
This is what I've managed to make so far and it still doesn't work. Any advice would be greatly appreciated.


1. Basic Information
The basic details for the rule, such as Name and Description


Module: Tasks
Rule Name: Remind when overdue
Status: Active
Description: Remind the task owner of overdue tasks.
