Is your select named like and array? 
i.e. <select name="foo[]" multi="multi">
...
</select>

then $ActionForm->Get(foo) should be an array.

Here is a snippet from the upcoming article that deals with a similar, but not
exact, issue:

From a smarty template (trimmed down):
{section name=g loop=$group}
{assign var=gid value=$group[g].link_group_id}
  {if $smarty.section.g.first}
    <form action="{$action_link}" method="post">
    <div>
    <table>
  {/if}
    <tr>
      <th colspan="2">
        {if $smarty.section.g.first}
          <input type="hidden" name="{$action}" value="UpdGroup" />
        {else}
          <hr />
        {/if}
        <h2>{$group[g].group_name}</h2>
      </th>
    </tr>
  <tr>
    <th>Name:</th>
    <td>
<!-- 
***********************
NOTICE THIS HIDDEN NAME 
***********************
-->
      <input type="hidden" name="groups[]" value="{$gid}" />
      <input type="text" name="group_name{$gid}" value="{$group[g].group_name}"
size="45" max="50" />
    </td>
  </tr>
  <tr>
    <th>Description:</th>
    <td><textarea name="group_desc{$gid}" rows="4"
cols="40">{$group[g].group_desc}</textarea></td>
  </tr>
  {if $smarty.section.g.last}
    <tr>
      <th colspan="2">
        <hr />
        <input type="submit" value="Update" />
      </th>
    </tr>
    </table>
    </div>
    </form>
  {/if}
{sectionelse}
  <h2>Warning</h2>
  <p>There are no groups, please add one.</p>
{/section}

And here is the extended ActionForm that processes it:
<?php
/**
 * GroupForm class definition
 *
 * @author  Jason E. Sweat
 * @since  2003-04-29
 * @package    PHP_Architect_MVC_links_example
 * @subpackage  Forms
 */

/**
 * GroupForm class definition
 * @package    PHP_Architect_MVC_links_example
 * @subpackage  Forms
 */
class GroupForm extends ActionForm
{
  /**
   * update list
   */
  var $_moUpdList;
  
  /**
   * override PutAll method for custom processing
   *
   * @param  array  $paIn  input array
   * @return  void
   */
  function PutAll($paIn)
  {
    Parent::PutAll($paIn);
    
    $a_list = array();
// notice that I expect groups to be an array here
    $a_loop = $this->Get('groups');
    if (is_array($a_loop)) {
      for ($i=&new ArrayIterator($a_loop); $i->IsValid(); $i->Next()) {
        $i_upd_key = (int)$i->GetCurrent();
        $a_add = array(
          'link_group_id'  => $i_upd_key
          ,'group_name'  => stripslashes($this->Get('group_name'.$i_upd_key))
          ,'group_desc'  => stripslashes($this->Get('group_desc'.$i_upd_key))
          );
        $a_list[] = $a_add;
      }
    }
    $this->_moUpdList =&new ArrayList($a_list);
  }
  
  /**
   * return list iterator for updates
   *
   * @return  object  list iterator
   */
  function &GetList()
  {
    return $this->_moUpdList->ListIterator();
  }
}

?>

Thank you.
