[Zope] (no subject)

[Luis Martín Argañaraz]

hello.
I´m a new Zope user and I have a problem whit the external methods. I´m reading Zope Book (Chapter 8:"ScriptingZope.html") and I can´t add that the external method "makeThumbnail", proposed there. It looks like zope doesn´t recognize the variable "self".
Any suggestion?
Thanks
