Thanks.  Sometimes "too easy" makes one feel really dumb.  I'm trying
to exploit all the capabilities of Ruport's tabling handling -- and
struggling.  I don't know why this is seeming so difficult.  I now get
an error when using group_by_tag.  In my data load, I've done the
following:

   def apply_category(r)
      case
      when r.proj[0,4] == 'ADMN'
         r.tag(:Administration)
      when r.task[0,5] == 'AL916'
         r.tag(:Support)
      when (r.task[0,2] == 'IS' or
            r.proj == '76011' or
            r.proj == '75634' or
            r.proj == '75638')
         r.tag(:Development)
      else
         r.tag(:Other)
      end
   end

When I attempt to utilize those tags, things go south.  I've
attempted:

   def cat_hours(c)
      hrs = 0
      t = @tbl_PAS.group_by_tag(c)
      #@tbl_PAS.group_by_tag(:Development).each {|r| hrs += r.whours}
      printf "%-15s = %5.2f\n",c,hrs
   end

But I am typically greeted with "Exception: undefined method
`group_by_tag' for #<Ruport::Data::Table:0x2d6c700>"

If you have any suggestions, that would be much appreciated.  What I
am doing is attempting to deal with the increased time reporting
demands of my company.  Their time tracking system is dismal, but it
exports data to Excel.  So I want to table everything, categorize it
at will, and produce six or seven different summaries from the various
data elements available.

thanks again,
