I am having difficulty replacing array elements with hash values using the following script. $string appears 8 times in my output file. I want to replace the first occurance with $header{1} amd the second with $header{2} and so on. Any help is appreciated! Thanks!

use Tk;
use strict;
use warnings;

my $mw=new MainWindow;
my $filename;
my $string;
my @data;
my $n;
my %header = ("FHT_neg45","FHT_0","FHT_45","FHT_90","OHT_neg45","OHT_0
+","OHT_45","OHT_90");
my $button = $mw->Button(-text=>"temp",
    -command=> \&button)->pack();
MainLoop;

sub button {
    #Read BJSFM_out.prn into an array @data
    $filename="BJSFM_out.prn";
    open(OUTPUT, "< $filename") or die "Can't find allowables.txt!";
    $string="Laminate Strain Allowables";
    @data=<OUTPUT>;
    $n=1;
    for (@data) {
        if ($_ eq $string) {
            s/$_/$header{$n}/;
            $n++;
        }
    }
    open (FILE, '>temp.txt');
    print FILE @data;
    close FILE;
}
