James,
Thanks for the help.  Unfortunately your suggestion did not work, i got
a NameError on "sayHellos" (which is a property of the RandomGreeting
folder.)

I managed to get it to work by two other ways.

<dtml-with RandomGreeting>
    <dtml-var Greet>
</dtml-with>

and

<dtml-var "RandomGreeting.Greet(RandomGreeting)">

I'm just beginning to understand the first way, however, I'm still
scratching
my head about how the second way works...

thanks again for the help,

teep
