Rules Help Please

Request for Rules help. Version 7.1.30794.0
I have created a simple rule (that’s easy using the wizard).
The rule is active as the check box is ticked.
The rule works if I run manually, using Apply rule.
Q1: The rule refuses to run On Receive. How do I debug this?
Q2: How do I change scope? I can’t find any reference to Rule Scope in the User Manual.
My rules scope are always “All Accounts”
Thank you
