This will only work if the PH226 can be _aquired_ from your current context 
object (check with "The Zope Book 2.7 edition" about _ACQUISITION_ - one of 
the Zope core concepts.

Acquisition also applies here.

tal:replace="python: getattr(context, x)"

An alternative to acquisition for getting an object is traveral 
(restrictedTraverse('/path/to/object').

I strongly recommend reading the basic Zope documentation first in order to 
understand how acquistion works.
