#### Method: radio_group
# Create a list of logically-linked radio buttons.
# Parameters:

Now what I'm wondering is how is it that you didn't happen to stumble accross the CGI documentation, or even its guts?

P.S. -- here's a few *secret* links, don't tell nobody ( CGI, How to RTFM, http://ovid.perlmonk.org, http://stein.cshl.org/, perlsec)

update: Whaza?

1) No the CGI documentation does not explicitly state how you can do what you want (you're doing some odd things, and it'd be crazy for the documentation to reflect that).

2) Nooooo, If you don't know how to use certain functions, or they're not documented to your satisfaction, just crack open CGI.pm (and yeah, you could borrow, but that wasn't my point)

3) Didn't mean to imply you should modify CGI.pm

Yes, you missed my point completely (I guess I should've been more explicit, kinda like jeffa up there).

I just wanted to point out to you, radio_group (which returns a list) and textfield, two CGI.pm functions, which *you* can use to solve your problem. You have to use your imagination as to how to do it (i ain't writing code like jeffa, ain't got time)

Hopefully that clarifies it (if not, update your reply).
 

Look ma', I'm on CPAN.
