thanks for the reply and the code. haven't been able to figure it out
myself :)
will keep trying.

I'm thiking something like:

def create_hierachy(csv_rows)
  csv_rows.each do |row|
    # New user hash
    user = {:user_name=>row['user_name'], :user_id=>row['user_id']}

    if row.is_supervisor=='t'
      # GET THE THE SUB-USERS
      users = csv_rows.collect{|r| r.supervisor_id==row.user_id}.compact
      user[:users] = create_hierarchy(users)
    end
  end
end

Just can't it it working :/
