I found the problem... I was putting a 'inc' DTML method in the product 'pHitCounter', instead of in it's class 'cHitCounter'.
Shawn, no, I don't need a counter yet. I was really trying ZClasses out by creating a HitCounter... I came on the idea when viewing the DTML-demos.
Q : Is this scenario possible :
Is it possible to show a piece of a picture on a form? I.e. you've a picture in Zope and you want to copy a rectangular part from this picture so you can show it somewhere else (only that piece).
I don't believe there is any way to do this through HTML or DTML, but certainly you could use the PIL (Python Imaging Library) to manipulate an image in an external method. This would basically have to be an external method which takes the parameters and is called from a properly constructed img tag, and returns straight gif code. The hard part would be making sure that the img tag passed the necessary information in. I don't know off hand, can an img tag include a query? If so, that'll do the job, otherwise you would have to figure out how SQL Methods do direct URL traversal and mimic it to hide the necessary information in the address portion of the URL.
