Ajax – jQuery – toggle() doesn’t work

I have trouble with One Word A Day.

Here is the sample code which also works (replace example.com by your blog address):

<script type='text/javascript' src='http://example.com/wp-admin/load-scripts.php?c=1&load=jquery,utils&ver='></script>

<script type="text/javascript">

	jQuery(document).ready(function(){
		jQuery("input[name=owad_daily_post]").change(function () {
			jQuery("#owad_post_settings").toggle('slow');
			});
		});

</script>

<form method="get">
<input type="radio" name="owad_daily_post" value="1"/> yes <br />
<input type="radio" name="owad_daily_post" value="0"/> no
</form>

<div id="owad_post_settings" style="display:none;">Test</div>

But toggle doesn’t work in the admin panel. I don’t know how to fix it. Can anyone help me?
