Re: Access Classes In Layout Help??

Now I see! So the set variables change depending on which view is showing
within the default.ctp. If I add this car action to the app_controller
(instead of car model) and set the variables there, will all the views have
access to that variable? How can I make a global "set" variable that comes
from a specific query?
