Hello

I am having some more difficulties with hashes and arrays.
In a nutshell I have a hash with a unique ID for each key. I also have an array with the first element is always a unique ID. I am trying to iterate through the hash keys and foreach key check if it exists in the array. If it does I need to update the value of the hash (for that key) to include the values in the list after the first element (If you get me!!)
Here is what I have, and it works for one array, but as soon as start introducing multi-arrays the data gets skewed. Because the actual script pulls its data from a database it might be difficult to dump the data here but assume one hash called %ret and one array called @lines. Typically, the script will look like this:

my @line1 = ('_W9C2JJDCB','<P>This is the problem1.</P>','<P>This is r
+es1</P>');
my @line2 = ('_W9C2JJDCB','<P>This is the problem2.</P>','<P>This is r
+es2</P>');
my @line3 = ('_W9C2JJDCB','<P>This is the problem3.</P>','<P>This is r
+es3</P>');

my @totlines;
push (@totlines,\@line1);
push (@totlines,\@line2);
push (@totlines,\@line3);

my @dir1 =('_W9C2JJDCB',
          '201200240',
          'TEST: IGNORE',
          'John Doe',
          'Closed',
          'HIP',
          'email@email.com',
          'email2@email.com',
          
      );
my %hash = ( '_W9C2JJDCB' => \@dir1);

#At this point I have one hash (which may have many key/values) and on
+e array which could have many array refs
[download]

# So this is what I am trying to do

for my $key(keys %hash) {
    my $value = $hash{$key};    
    my @arr = @$value;
    foreach my $u(@totlines)
        {
                 if(@$u[0] == $key) 
                  {
          #print "$key @arr --- @$u\n";
          push (@arr,@$u);
           $hash{$key} = \@arr; 
                     }
    }
}
print Dumper %ret;

Now, the problem is that once the hash grows to more than one key the loops starts polluting the values with other array elements.

I appreiciate this is really hard to even explain correctly but I am hoping some will see some flaw in my logic in the "for key" loop?

EDIT: Of course an IF statement somewhere might help - added IF statement
