Use <code> tags, not <DATA>.

To get the grand totals, add the following as the last line inside the WHILE loop: 

  $h{$k1}{$k2}{+substr($k3,0,10) . "  Grand Total"} += $val;

This is a kludgy way to do it, but, given your sparse data definition, it does put out a grand total.

A more robust implementation would require one more level of hashing - I leave that as an exercise for you to implement.
