While going through the tutorial (Zope 2.5.1 linux), I encountered no conspicuous problems until I got to lesson 8. In lesson 8, I altered the photoAction document as specified in the instructions, by adding ", title=photo_title" after "file=file" (and saving the changes). Then I attempted to view the document by clicking the View tab, whereupon Zope returned an error: Error Type: NameError Error Value: global name 'file' is not defined I took a guess at the problem, added double quotes around the "file" after "file=", saved the changes and tried again to view it; the same error was returned; I changed the double quotes to single and voila! a new error was returned: Error Type: NameError Error Value: global name 'photo_title' is not defined Okay, I saved a step this time by going straight to single quotes around "photo_title", saved the changes, clicked the View tab, whereupon a new error was returned: Error Type: Bad Request Error Value: Empty or invalid id specified. This time my guess worked the first time: I put something between the (formerly empty) single quotes after "id=", clicked View, and got the expected result. Is this the right place for this kind of report? Steer me to the right place if not. Eric
