[Zope] Lost in name Space...

Hi,
Zope newbie here, a bit lost on namespaces...

I have created a folder in the zope root called "RandomGreeting".  
Inside this folder, there is one DTML METHOD called "Greet".  "Greet" 
contains the following line:

<p><dtml-var expr="_.whrandom.choice(sayHellos)"></p>

"sayHellos" is a property of the "RandomGreeting" folder, and 
contains 4 lines which are various ways to say 
hello : "Ola","Hi","Bonjour","Sawasdi".  The purpose of this method
is to print out a random greeting.

Everytime i click "View" for this DTML Method, i get a random hello.  
Fine, that is exactly what I want.

The problem is that I am trying to use this "method" from its parent 
folder (the root folder as a matter of fact).  I have inserted the 
following bit into the top level "index_html" DTML Method of my Zope 
root near the begining, so that it produces a random hello on the 
front page everytime someone accesses it.

I have tried :
<dtml-var RandomGreeting.Greet>
<dtml-var RandomGreeting.Greet()>
<dtml-var "RandomGreeting.Greet()">
<dtml-var /RandomGreeting/Greet>

all of these, to know avail.  I am getting either a NameError or 
KeyError.  I am pretty sure I'm missing a simple concept here. It is 
possible to call functions from child objects is it not? 

Please help with some enlightenment.  Many thanks in advance.
