Hope someone can help.

I am trying to set the Date/Time on the Menu Bar to show the date and times as the following:

Friday, October 21, 2016 9:00 AM.

I go to "System Preferences/Date & Time/Open Language & Region/Advanced/Dates" to tweak the look I want.

I can highlight the FULL option, but I do not know how to set it. The instructions are to "drag" the choice, BUT to where? When I try to drag the box to the bar, the selection just slides back to the box. No matter what I click on/select, the changes do not take place for the DATE.

Obviously, I am missing something about the procedure. Is there a special knack for setting this?
