Problem calling this template

I am calling the below recursive template Records incorrectly. Could
someone please help me see the problem? Recursion isn't working.

<Records>
      <Record>
              <service>1</service>
              <hours>191.25</hours>
      </Record>
      <Record>
              <service>2</service>
              <hours>532.25</hours>
      </Record>
      <Record>
              <service>3</service>
              <hours>32</hours>
      </Record>
      <Record>
              <service>4</service>
              <hours>2858.5</hours>
      </Record>
      <Record>
              <service>5</service>
              <hours>244.3</hours>
      </Record>
<!--  etc -->
