[FRPythoneers] Zope scope question

I'm wondering if anyone can give me a clue on using or parsing scope 
issues in zope.

I'm working on a zope + database application where I need to edit 
existing database records. What I'm doing works very well up to a point. 
I've created a dtml method which is a cgi form. It send's it's value to 
another dtml method which uses a <dtml-in > (to a zmysql method)to grab 
the record data and fill it into another cgi form. That form send's the 
revised data to another zmysql method. This all works fine when running 
the original dtml method as itself or imbedded in a dtml document.

What I'm running into is that if I embed the first dtml method into the 
result of another query - like showing all records from a particular 
date - I run into a format change for the passed form element I don't 
know how to deal with. Specifically: Normally if I enter the value 109 
into the form, the value passed to the next method is 106. It works 
fine, I expect it and use it that way. When I go out of scope, the 
passed value is ['106','']. This messes up my query and I get no matches.

I had originally thought that the problem was related to having the 
calling form in a directory above the called method. This turned out to 
not be the case as it happens when they are in the same directory.

I also copied the content of the cgi form method into the results page 
directly (not using the <dtml-var> tag to call it. This didn't make any 

I've tried using <dtml-with REQUEST>  when looking up the passed value, 
but the result is the same.

Any hints on how I can get a clean value or parse the value so I could 
use it without resorting to a python script ?
