Two instances with different toolbars

I'm tryng to use 2 instances,
one with mytoobar and another with basic.
But is show the FULL in the first instance (sometimes works).

With only one, mytoolbar works very well.
(sorry, apologise my english).

<script type="text/javascript">
// first - with my tool bar , but show full
CKEDITOR.replace( 'details' ,
{
customConfig : 'ckeditor_config.js'
});
</script>

<script type="text/javascript">
//second, works.
// if delete this instance, the firs works with my tool bar
CKEDITOR.replace( 'homedetails',
{
toolbar : 'Basic'
});
</script>
CKEDITOR.editorConfig = function( config )
{
config.toolbar = 'Fax';
config.toolbar_Fax =
[
['Source','-','Cut','Copy','Paste','PasteText','PasteFromWord','-','Scayt'],
['Undo','Redo','-','Find','Replace','-','SelectAll'],
['Image','Table'],
'/',
['Styles','Format'],
['Bold','Italic','Strike'],
['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'],
['Link','Unlink']
];
};
