( #3333=superdoc: print w/ replies, xml ) Need Help??

I made this program, but it is giving so many errors. Can you help me in debugging it.

use strict; use warnings; use Carp qw(croak); { my $input_file = "input_file.txt"; my @lines = slurp($input_file); for my $line (@lines){ my ($filename, $ligand) = split(/\t/, $line); open(FILE, '<', $filename) or die "Cannot open file: $!"; while (my $line = <FILE>) { if ($line =~ /$ligand/) { $count++; $first=substr($line, 0,1); if($first=='H'); { $sum++; } } print "Total No. of interactions are $count"; print " No. of Hydrogen bonds are $sum"; } close(FILE); } } ##Slurps a file into a list sub slurp { my ($file) = @_; my (@data, @data_chomped); open IN, "<", $file or croak "can't open $file\n"; @data = <IN>; for my $line (@data){ chomp($line); push (@data_chomped, $line); } close IN; return (@data_chomped); }
