Hi all lords of perl,

I am new at perl and wish to seek information about how i can solve my problem, as the code follows shows, I have 2 files(one of data and the other keyword) I have created 2 arrays using these files and using the keyword array i wish to seek matching words from my data array using it. But cant seem to do a match using this statement if ($element =~ m/$tempwd/i)? Can any wise advisors guide me on this? thanks 
#!/usr/local/bin/perl -w

use strict;

open(INPUT, "data.txt") || die "Error opening 'keywd.txt'\n";
my @data = <INPUT>;
open(FH, '<', "keywd.txt") || die "Error opening 'data.txt'\n";
my @keywd = <FH>;
my $keywdnum = $#keywd;

while (my $element = pop @data)
{
    my $i = 0 ;
    chomp($element);
    while ($i <= $keywdnum-1)
    { 
    my $tempwd = "";
    $tempwd = $keywd[$i];

    if ($element =~ m/$tempwd/i)
    { print $i;
      $i++;
    }
        else 
    { 
        $i++;   
        }
       }
   
}
close INPUT;
close FH;
