Need Help Modifying Select Menu Javascript

[JeffGSR]

I have a JavaScript script that takes selected options from one menu and transfers it over to another menu. The script works fine when I don't have any other form elements on the page, but when I add the search field to the page I get an error. See screenshot. I need to include the search the box on this page. How should I modify the Javascript in order for it to work with the search box being on the page? Thanks.

function allSelect()
 
{
 
  List = document.forms[0].chosen;
 
  if (List.length && List.options[0].value == 'temp') return;
 
  for (i=0;i<List.length;i++)
 
  {
 
     List.options[i].selected = true;
 
  }
 
}
 
 
 
function copyToList(from,to)
 
{
 
  fromList = document.forms[0].elements[from];
 
  toList = document.forms[0].elements[to];
 
 
 
  if (toList.options.length > 0 && toList.options[0].value == 'temp')
 
  {
 
    toList.options.length = 0;
 
  }
 
  var sel = false;
 
  for (i=0;i<fromList.options.length;i++)
 
  {
 
    var current = fromList.options[i];
 
    if (current.selected)
 
    {
 
      sel = true;
 
      if (current.value == 'temp')
 
      {
 
        alert ('You cannot move this text!');
 
        return;
 
      }
 
      txt = current.text;
 
      val = current.value;
 
      toList.options[toList.length] = new Option(txt,val);
 
      fromList.options[i] = null;
 
      i--;
 
    }
 
  }
 
  if (!sel) alert ('You haven\'t selected any options!');
 
}
