Got it!!! Thanks. Here is the code: 
sub Combobox1action {
    my( $self, $event ) = @_;
    my $selection;
    
    $selection = $event->GetString();
    
    $self->SetTitle( 'Combo box selected ( '.$selection.' )' );
}

I guess I still need to clean up a little, but at least I've moved forward. Thanks all. Any other final suggestions are welcome.
