Plesk 8.3 Awstats Jump Menu Javacrip Error

[energylevel]

Has anyone else noticed the jump menu for previous months in Awstats doesn't work, there is a javascript error:

Error 'top.mainFrame' is null or not an object

Anyone managed to fix this, I tinkered with the script but couldn't get it working ??

OK I sorted this, if you change script to this it should work:

<script language="JavaScript">
<!-- hide
function change_page()
{
parent.mainFrame.location=document.periodForm.periodSelect.value + '/index.html';
}
// -->
</script>
