Thank, that solved the problem. now i would like ask in addition, how could i add an additional single hash to a line i ($i) of my array of hashes after the line: 
 
push( @{$Array_ref} , \%hash );

[download]
for example, i create my array of hashes (in a thread) and then send the array of hashes reference to an additional function. Then i tried (in the new function) 
  
@Array = @$Array_ref;
$Array[$i]{'foo'}->$boo

[download]
once i tired to call the new hash (in line i)  $Array[$i]{'foo'} i got an error massage of uninitialized value. I can think of the reason why it is like that and that is since my new hash i am trying to add is not "shared"... but i dont know how to add a single shared hash to $Array$i. thanks
