Dylan,
Thank you so much. With a little tweaking, I finally got it working.
Here is how I had to do it since I was using the Catalog to produce the
addresses. sequence-item does not work with the Catalog, all it does it
produce:
<mybrains instance at 8b526e0>
<mybrains instance at 89c55f8>
<mybrains instance at 8a97c18>
so I used:
<dtml-call "REQUEST.set('my_names', [])">
<dtml-with testList>
<dtml-in Catalog>
<dtml-call "my_names.append(email_address)">
</dtml-in>
</dtml-with>
and then your code inside the sendmail tag.
Bcc: <dtml-var "','.join(my_names)">
Thanks Again,
Michael
