Thanks for the quick answer. nr.1 - copy-paste error. nr.2 - 100% RIGHT. nr.3 - understand. nr.4 - fast writing error :-) Sorry, code nr.4 is not good for "since you want to exit the loop when a certain key is reached" because I want to create a hash element if the has key is not there. For now I use the "defined" function (below) to do the work but I realy want to know if there is other solution. 

unless ( defined $email{"email"} ) {
    $email{$html->param("email")}=$html->param("name");
}
