An easier way of doing this is with the CGI module... pass a CGI object (in=
 this case 'q') to the template and you can do fun stuff like:

[% q.radio_group(name =3D> 'GETS_REPORT',
			values=3D>['T','F'],
			default=3D>gets_report,
			labels=3D>{'T'=3D>'Yes','F'=3D>'No'}
		); %]

If you want to get fancier you make stuff persistent:

[% SET TFlabels =3D {'T'=3D>'Yes','F'=3D>'No'}; %]
[% SET TFvalues =3D ['T','F']; %]
[% q.radio_group(name =3D> 'GETS_REPORT',
			values=3D>TFvalues,
			default=3D>q.param('GETS_REPORT'),
			labels=3D>TFlabels}
		); %]

And you can then add more radio groups with the same params dead simply... =
Like say you have an array of questions in a hash with the keys as labels

[% SET TFlabels =3D {'T'=3D>'Yes','F'=3D>'No'}; %]
[% SET TFvalues =3D ['T','F']; %]
[% FOREACH question =3D questions.keys %]
	[% q.radio_group(name =3D> question,
			values=3D>TFvalues,
			default=3D>q.param(questions.$question),
			labels=3D>TFlabels}
		); %]
[% END %]

VOILA!

BTW... I have noticed that most of the people asking questions and showing =
DBI examples and such seem to hardcode their HTML... am I doing something e=
vil by using the CGI module for all this?

For me at least I love the fact that it handles all the formatting.. keeps =
the html 100% standards compliant and generates things like popup groups an=
d multi selects with ease.

Is there some big performance hit that I am missing? :}
