A sneaky problem indeed, and once again, one caused by "convenient" 
shortcuts. (o8

The simple answer:  use REQUEST.form['FOO']  to refer to the form variable.

The longer answer:

To make life simpler on our key-weary fingers, DC made all the form variables 
part of the namespace, but put then sufficiently down the search path so they 
wouldn't get in the way of other objects.  Most of the time this is just 
great, but occasionaly you do run into this problem.

So, you can explicitly access all form variables with REQUEST.form[]... just 
as you can access all cookies via REQUEST.cookies[] 

I would advise you make a small DTML Document containing <dtml-var REQUEST> 
just to have a look at what it contains.... THEN go and check up the ZQR for 
all the members of REQUEST... and RESPONSE, while you're at it.. (o8
