I am trying to add the returned values from a hash to get the combined total value for the same key. 
ID,Value
FB208025,1629.01
FB208025,1201.16


FB091027,1257.66
FB091027,741.92

FB135022,11210.66
FB135022,3238.67
FB135022,3569.34
FB135022,5534.23

I want to get total combined value for each ID:
FB135022=11210.66+3238.67+3569.34+5534.23

my %baldata;
while (defined($line = <IN>)) {
   if ($line =~/caus/){
      $ACTNUM = (split(/\t/,$line))[0];
      $CSHBAL1 = (split(/\t/,$line))[17] ;
      $baldata{$ACTNUM}{$CSHBAL1} = ($ACTNUM,$CSHBAL1);
      $CSHBAL2 = $baldata{$ACTNUM}{$CSHBAL1};
      print "$ACTNUM,$CSHBAL1,$CSHBAL2\n";
   }
}

I can get the value for each KEYID everytime it appears, just can not 
+figure out how to add the values up for each individual ID.  Any help
+ will be appreciated.
