[Zope] Testing for Equality

[CLIFFORD ILKAY]

Hi Hans,

That has to be the problem. In thinking about my approach to solve the 
problem of saving the state of form variables over multiple forms, I think 
it is flawed. Consider this.

Form1 -> Form2 -> Form3 -> Save data collected over the previous 3 forms in 
DBMS.

Form3 will not have access to Form1's variables unless I go through the 
ugly exercise of having a bunch of hidden fields, just like SAME_RESIDENCE 
in my original example. That seems like an awful lot of work to go through. 
Can you suggest any alternative approaches?
