my $cr_line; 
my $i = 1;
my ($is_an_error_entry,$is_a_warning_entry);
my $resolution_link;
my (%seen_cr,%seen_match,%seen_link) ;
my ($crline,$Buggyfile,$resolutionlink,$match);

#subroutine for errors
 sub error_entry
    {
print "in error entry";#not getting printed
my $workbook = Spreadsheet::WriteExcel->new("errors.xls"); 
my $worksheet = $workbook->addworksheet("Error");
    if ($match =~ /Error:/) { 
        $is_an_error_entry = 1; 
        next LINE; 
    }  
    if ($match =~ /https?:/) {
        if ($is_an_error_entry) { 
    ($resolution_link) = $match =~/(https?:\S+?)[.]?\s/;
        }
   
    }

    }
#subroutine for warnings
     sub warning_entry

    {
my $workbook = Spreadsheet::WriteExcel->new("warnings.xls"); 
my $worksheet = $workbook->addworksheet("warnings");
    if ($match =~ /Warning:/) { 
        $is_a_warning_entry = 1; 

    }  
    if ($match =~ /https?:/) {
        if ($is_a_warning_entry) { 
    ($resolution_link) = $match =~/(https?:\S+?)[.]?\s/;

                $crline = $cr_line;
             }

            print $crline, $match, $resolution_link, "\n"; 
            $worksheet->write( $i, 0, $crline ); 
            $worksheet->write( $i, 1, $match ); 
            $worksheet->write( $i, 2, $resolution_link );
