Hi all. I'm stumped. I've been toying with a small financial application using Perl/Tk and I've come across what I think is a scope problem, but it sure doesn't make sense to me. I'm attempting to call a subroutine from a button and pass the value that is supposed to be set from a radiobutton. Like this: 
-command => [\&Account_Setup, $acct]

$acct gets set with a radio button variable: 
$f->Radiobutton(-text => "Investment",
    -value => "investment",
    -variable => \$acct)->pack(-side => 'top',
                                   -anchor => 'w');

[download]
The subroutine contains a simple print statement for testing: 
sub Account_Setup{
    my ($acct_type) = shift;
    print "Account Type: $acct_type\n";
}

[download]
The problem is, the button code above doesn't seem to be passing the value stored in $acct. However, this code on the button works: 
-command => sub{ print "Account: $acct\n"; }

In addition, if I set the value of $acct right before passing it, the subroutine seems to work fine as well. Is this some sort of scope problem or am I missing something really obvious? Any suggestions would be greatly appreciated. TIA.
