[Zope] NameError in Zope Tutorial Lesson 8

Hello listmembers, I am fairly new to Zope and turning debugging on and googling a lot does not lead me to the solution of the problem. Learning Zope I got this error trying out lesson 8(cont.): <--snip--> Error Type: NameError Error Value: global name 'title' is not defined <--snap--> Zope version: 2.7.7 Python: 2.3.5 OS: FreeBSD 4.11-STABLE Please can anybody give me a hint. I simply can't await to get my Elvis Photo Archive up and running. TIA Norbert
