...because you're missing some " "

REQUEST.form['FOO'] is a python expression.

<dtml-if REQUEST.form['FOO']> is short for <dtml-var
name="REQUEST.form['FOO']">

so, unless you have a folder or document names 'REQUEST.form['FOO']', it
will return false :-S

What you want is <dtml-if "REQUEST.form['FOO']">, which is short for
<dtml-if expr="REQUEST.form['FOO']">.

This evaluates expr as a python expression...

...an oddity of ZSQL methods :-( The REQUEST usually gets made available
in the namespace, but in ZSQL methods, only the parameters your specify
as 'arguments' get added to the namespace. At a guess, try adding
REQUEST to the 'Arguments' list...

good luck,
