Outlook Contacts field missing in Publisher mail merge

OS: Windows XP SP3
Softwa MS Office 2003
I am helping set up a friend so he can print birthday cards for his clients
from Publisher. I've created a card in Publisher and have it set up to use
mail merge. I am using his Outlook Contacts as the data source.

I want to be able to filter the recipient list in Publisher by the Birthday
field from his Outlook Contacts. However, the Birthday field does not show up
as a column in the Publisher recipient list when I select Edit recipient
list... in the mail merge wizard.

I cannot figure out how to get the Birthday field included in the mail merge
recipient list. I have the Birthday field included in the active view in
Outlook, but that doesn't seem to be the source from which the recipient list
is pulled.

Any ideas/suggestions/solutions?

Thank you,
Steve
