Good Morning! I have this problem, i hope you can help me: 

use strict;
use warnings;
use Data::Dumper;
open (FILE, "/Users/Pabli/Desktop/gene_association.goa_human");
open (FILE2, "/Users/Pabli/Desktop/go3.obo");  
while(<FILE>) { 
                   
    my @array_with_all_fields=split(/\t/);
    if ($array_with_all_fields[2] eq "TP53"){
     
       my $mio=$array_with_all_fields[4];
       my %go_accession_hash=($mio,'');
       
   my @test2= keys %go_accession_hash;
   
   }
    }
 
        
while(<FILE2>){
    
    print "".$test2[0]."\n";
    
}  
  

close FILE;
close FILE2;

When the compiler enter into the second while the variable "test2" is not seen! I try to "play"with the declaration global/local...but the result is the same! Can someone help me?

Thanks Paola
