[Zope] Form Data Needed in Second Form

I have part of a Zope app written largely as Python scripts linking DTML forms that looks conceptually like this: 1. Form A gathers data and then as its action invokes a Python script. 2. Python Script 1 creates a new DTML document and updates its contents based on field data in Form 1. 3. Python Script 1 then uses RESPONSE.redirect() to open a second DTML form, Form 2. 4. Form 2 needs the name of the document Python Script 1 created as well as access to some or all of the data in the fields in Form 1. What is the best/right/only way to accomplish this goal? Seems like it should be straight-forward but I've played with several promising ideas that turned out to be dead ends. I'm getting a bit desperate. All help appreciated!
