Yes it has to do with how the date is displayed.  Here is what I have so far
and  below that is a sample of what is being returned.  There will always be
a start and end date, but the number of members is not always consistant and
the data for each person is very inconsistant.  So the mail merge has more
blank listings then current members so if any members get added they will
automatically be included when I mail merge and all of the headings and
spaces are part of the merge fields (MERGEFIELD  WORK_FAX \b "Bus. fax: " )
so if someone doesn't have a Bus. fax then it won't say Bus. fax with a blank
after it.
