Here's the error message: Use of uninitialized value in concatenation (.) or string at SR/Dtest.pm line 16 (#1) That points to this line: 
$self->Label(-text=>"var= $optnum")->pack();

If I'm understanding correctly, it indicates $optnum is undefined. If that is so, then the problem must lie with this line: 
my $optnum = $self->optionGet('Target','Dtest');

I'll crack the books and check into the debugger ASAP.
