// relevant JavaScript:
function loadGroups()
{
   var group = document.getElementById("jobGroup");
   group.length=groupArray.length; // <-- error here!
   for(var i=0; i<groupArray.length; i++)
   {
      group.options[i].text = groupArray[i].groupName;
      group.options[i].value = groupArray[i].groupId;
   }
}

<!-- relevant HTML -->
<select size="5" class="select" name="jobGroup" onChange="changeType();">
</select>


Reproducible: Always
Steps to Reproduce:
Go to http://www.jobcentreplus.gov.uk/cms.asp?Page=/Home/Customers/Searchforajob

The bug occurs in the iframe object. The box beneath "Select a Job Group from
the list" (the "jobGroup" object) should contain a list of items generated by
the JavaScript code highlighted above.
Actual Results:  
Nothing appears in the select box.

Expected Results:  
Displayed a list of items in the select box as generated by the JavaScript code.
because groupArray is not defined you cannot determine the length either
groupArray is defined in a html/head/script element, so this is not the 
problem. The following is a cut-down version of the problem:

-- begin --
<html><head>
<script>

function loadGroups()
{
   var group = document.getElementById("demo");
   group.length = 10; // error: group has no properties
   for( var i = 0; i < 10; ++i )
   {
      group.options[i].text  = "select " + i;
      group.options[i].value = "id" + i;
   }
}

</script>
</head><body onload = "loadGroups()">
<form><select size = "5" name = "demo"></select></form>
</body></hrml>
-- end --

Is this correct? MS IE6sp2 displays this ok.
