InsertHTML v2 rc3 issue

I am trying to use the insertHTML and it is not working in either IE or FF. Can anyone assist?

In the header I have:

<script src="/mlist/fckEditor/fckeditor.js" type="text/javascript"></script>
<script type="text/javascript">
function insertHTML(html)
{
var oFCKeditor= FCKeditorAPI.GetInstance('templateContent');
oFCKeditor.InsertHtml();
}
</script>


In the body I am using the following to invoke the FCK:


<script type="text/javascript">
<!--
var oFCKeditor = new FCKeditor( 'templateContent' ) ;
oFCKeditor.BasePath = '/mlist/FCKeditor/' ;
oFCKeditor.Value = 'test.' ;
oFCKeditor.Create() ;
//-->
</script>


And to insert the HTML:


<select>
<option value="">Select Template</option>
<option value="This is my HTML1">1</option>
<option value="This is my HTML2">2</option>
<option value="This is my HTML3">3</option>
</select>
<input type="button" value="Insert template" onclick="InsertHTML();">
