I'm not sure right now, but did you tried to put the script inside of script tags at the bottom of your page.
Or in the head tags,

Code:

<script langauge="javascript" type="text/javascript">
document.onload = function() {
   form.submit();
}
</script>

edit:

How is your form named, "forms" or "post".
