How do I get the "Received Value" for client Discovery?

[ComputerHabit]

Examples show using Received Value= Linux or Windows.

When I try to use this discovery does not work.

How could I put this in a custom email to see what the value is?

I have verified that the directions on this page are incorrect.

When I create a rule as exhibited in the link above discovery fails to execute.

Okay I realized that I was using "EQUALS" and not "LIKE" in my evaluation.
