[Zope] Using Z Classes...

Hi! I've created a Z Class named ZCounter with the following methods: GetCount InitCounter SetExclude It has the usuall add and factory stuff too. I've checked out the documentation, and they say how to make a Z Class object, but how do I use one? They didn't seem to have any examples. How, for instance, would I use the method GetCount that is in the ZCounter? Thanks! Donner
