Well, not so fast. I was really excited when I saw that last reply last night because it seemed like just a stupid programmer error. I can deal with that. I had shut down my PC by then and I haven't been able to get back to it until now (gotta work for a living during the day).

So I put in the echo but STILL no luck. Then I went back to basics. I built the form controller and view as described in CI documentation here.

I just added some radio buttons explicitly (without loop as in my code) and it repopulated the proper radio button on submit. Then I added another radio button group but generated it with a loop this time. Worked like a charm also. As long as I had an empty validation rule in controller.

That made me think "maybe I just typed something wrong in my validation rule". Checked and checked but I just don't see it.

Sorry for the long post but I'm pulling out what little hair I have left. Any help would be greatly appreciated.

Here's the sample form controller and view that works just fine
FORM CONTROLLER

Code:
&lt;?php

class Form extends CI_Controller {

 function index()  {

  $this->load->helper(array('form', 'url'));

  $this->load->library('form_validation');

  $this->form_validation->set_rules('email', 'Email', 'required');

  $this->form_validation->set_rules('volDate', 'volDate', '');

  $this->form_validation->set_rules('volDate2', 'volDate2', '');

  if ($this->form_validation->run() == FALSE) {

   $this->load->view('myform');

  } else {

   $this->load->view('formsuccess');

  }

 }

}

?&gt;

FORM VIEW

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;My Form&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;?php echo validation_errors(); ?&gt;

&lt;?php echo form_open('form'); ?&gt;

<h5>Email Address</h5>

&lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?&gt;" size="50" /&gt;

<h5>Explicit</h5>

&lt;input type="radio" value="Mon" name="volDate" id="volDate" &lt;?php echo set_radio('volDate', "Mon");?&gt;/&gt;Monday&nbsp;&nbsp;

&lt;input type="radio" value="Tue" name="volDate" id="volDate" &lt;?php echo set_radio('volDate', "Tue");?&gt;/&gt;Tuesday&nbsp;&nbsp;

&lt;input type="radio" value="Wed" name="volDate" id="volDate" &lt;?php echo set_radio('volDate', "Wed");?&gt;/&gt;Wednesday&nbsp;&nbsp;

&lt;input type="radio" value="Thu" name="volDate" id="volDate" &lt;?php echo set_radio('volDate', "Thu");?&gt;/&gt;Thurday&nbsp;&nbsp;

&lt;input type="radio" value="Fri" name="volDate" id="volDate" &lt;?php echo set_radio('volDate', "Fri");?&gt;/&gt;Friday&nbsp;&nbsp;

<h5>With Loop</h5>

&lt;?php

$days2 = array("dateID" => 1, "day" => "Mon");

array_push($days2, array("dateID" => 2, "day" => "Tue"));

array_push($days2, array("dateID" => 3, "day" => "Wed"));

array_push($days2, array("dateID" => 4, "day" => "Thu"));

array_push($days2, array("dateID" => 5, "day" => "Fri"));

foreach ($days2 as $day2) {

  $val2 = $day2['dateID'];

?&gt;

&lt;input type="radio" value="&lt;?php echo $val2;?&gt;" name="volDate2" id="volDate2"&lt;?php echo set_radio('volDate2', $val2);?&gt;/&gt;&lt;?php echo $day2['day']; ?&gt;&nbsp;&nbsp;

&lt;?php } ?&gt;

<div>&lt;input type="submit" value="Submit" /&gt;&lt;/div>

&lt;/form&gt;

&lt;/body&gt;

&lt;/html&gt;

Now here are snippets of my code that does NOT work:
CONTROLLER

Code:
...

 $this->form_validation->set_rules('volDate', 'Date', '');

    $this->form_validation->set_rules('volSite', 'Site', '');

...

VIEW

Code:
...

&lt;?php

echo "<b>Step 1: Select a date</b><br />&nbsp;&nbsp;";

foreach ($days as $day) {

  $val = $day['dateID'];

?&gt;

&lt;input type="radio" value="&lt;?php echo $val;?&gt;" name="volDate" id="volDate"&lt;?php echo set_radio('volDate', $val);?&gt;/&gt;&lt;?php echo $day['day']; ?&gt;&nbsp;&nbsp;

&lt;?php } ?&gt;

<br>

&lt;?php

echo "<br /><b>Step 2: Select a location</b><br />&nbsp;&nbsp;";

foreach ($sites as $site) {

  $val = $site['siteID'];

  echo '&lt;input type="radio" value="'.$val.'" name="volSite" id="volSite"&gt;'.$site['name'].set_radio('volSite', $val).'&nbsp;&nbsp;';

}

?&gt;
