Why won't this code update the value in question properly?

This bit of code is supposed to update a string value when called, but it doesn't. It simply returns an error pointing to it. Anyone know why?

Also, is there any easy way to just get it to read out the hour and minute instead of having it read out seconds, too?

        func = function( p ) -- functions go HERE
            print(p.Name .. " locked the back door!")
		game.Workspace.FaraVoice.Value = ("It is currently " .. game.Lighting.TimeOfDay ", sir.")
		end
