Well, I see a path through this code that would result in categoryID not being
set in the view. Do you? When function index is called without a parameter
(i.e. when you access a URL without the id), then $this->set('categoryID',
$categoryID) is not called, hence categoryID is not set in the view, hence PHP
tells you that.
If you're going to set up your controller's index method that way (where the
categoryID is optional), then you need to code your index template to allow
categoryID to be optional as well.
