I am using the sort method to sort names I retrieve from a database. Initially it works but if I try to access this same method a second time without closing out of my program, I get the following error 
Use of uninitialized value in string comparison (cmp) at bppcsvver.pl 
+line 539.

Here is my code: 
my $a_user= $activeuserName;
    my %AccountHash;
    my @activeUserAccts=();
    my $activeUserCount=0;

      @activeUserAccts = sort{$a->{acct_name} cmp $b->{acct_name}} BPP
+::ACCOUNT->getActiveUser($activeuser);
    $activeUserCount = @activeUserAccts;
   
    my $active_user_acct = $acct_frame->Optionmenu(-options=>[map {[$_
+->{acct_name}=>$_->{acct_id}]} @activeUserAccts], -command=>sub {},-v
+ariable=>\$activeUserAccts[0], -width=>25 )->grid(-row=>3, -column=>1
+,-sticky=>'nw');   
    $active_user_acct->addOptions(" ");
