[Zope] newbie question; getting started

Hi folks, I found zope rather cool, curently I'm evaluating. But I can't get it working for real. I want to do a rather simple thing zope does all the time. But I spent many hour right now failing to figure out how. I have a form, which posts to a method. The method shall a) increment a persistent counter b) put the content of one of the form fields into a new object (I assume I want to use a document here?). The name of the new object shall be derived from the counter above. Better yet it would modify another document sticking it somewhere into the middle. But I think that would make it too complicated for now. Done. Stupid me, but I can't get myself over that starter problem. Thanks for each and every hint. /Jerry
