SQL 2008 SQL Server Agents Jobs, how to populate email for Notifications

I am trying to add my email address to notifications for SQL Server Agent Job when it fails..

So I go SQL Server agent, open up the jobs, right click on the job and select properties and then notifications. I can check email there and have to select email address from a dropdown but the dropdown is blank and can't edit it..

Any Ideas

You need to first create an operator for the SQL Agent to use. Under the SQL Server Agent folder, right click on the Operators folder and select "New Operator..." Supply a name for the operator and an email address. You'll then select this operator by the name you chose in the Notifications drop down for the job.
