Thanks for your help. My PI doesn't want me to use any other modules other then the default ones that come installed with perl, so I can't use List::Util. I already have the the column assigned to a 1D array on line 121, but I believe it is all referenced. If I try to use this sub with a passed in @col, the total is calculated incorrectly. 

sub score_count {
    my @arr = shift;
    my $total = 0;
    foreach my $score (@arr) {
      print "@$score ";       ##prints actual values; If @ taken out, 
+values printed are like ARRAY(0x95533e0)
    $total += @$score;    ##if @ is taken out the summation is somewhe
+re ~140915576; however, with the @, the values are still incorrect. 
    }
    print "$total\n";
    return $total;
}

Are you suggesting to not even use the column slice so it's a 1D array?

Thanks for letting me know about if construct issue but I do want to skip the line if it is false so that code should be correct.

Thanks for the help
