[Zope] How do I edit values of items created using Property Sheets

Hello, I am new to Zope, so this might be a FAQ, but my seraches of the Zope archives and website didn't come up with anything. I have created a Zope application (phoebe.rider.edu:8080/Athena). I am using a Z Class with Property Sheets to define the fields for each of my entries. The entries are created using a form on my Zope site. My question is, is there any document, instructions, how-to, etc., that can tell me how to edit the entries once they are submitted? Ed Corrado ecorrado@hera.rider.edu
