The radio_group code you provided is pretty close to what I started out with, I just couldn't get it to work with the JavaScript. And I couldn't get CGI to spit out a single radio_group using both the hideEmail and showEmail ID's. I think my real problem is sticking with CGI beyond it's usefulness. I've been checking out templating systems for a couple months, but I'm adding to an application that's been around for a lot longer. Any new development will likely be using TT.

What I've done in the last few minutes is this, which works correctly, but it just seems wrong to make two calls to radio_group, each with one button. That's due to the JavaScript needing two different id's as currenly written.

'Show Email:',
$q->radio_group(
  -id => 'hideEmail',
  -name => 'radioEmail',
  -values => 'No',
  -default => 'No',
  -onclick => 'toggleEmail(event)'
),
$q->radio_group(
  -id => 'showEmail',
  -name => 'radioEmail',
  -values => 'Yes',
  -default => 'No',
  -onclick => 'toggleEmail(event)'
),
