Thanks for the response.
I tried this bit here to log in. With different form names.
But, this works. So, I can log in using the following.
my $mech = LWP::UserAgent->new;
'admin' => 'secret'
I can get to the correct page, as I mentioned. So, now I will try to select and de-select the radio buttons. I have one example of selecting the radio buttons. I'll give it a whirl. Again, using the Perl modules and oo is totally new to me.
