Form working on one page but not another

Question

I have a form that we have been using for years on our Joomla 2.5 site. After upgrading to Joomla 3.4 the form no longer works properly. The form is to order a book, and on submit, it sends an email to us then transfers the user to paypal to finish the transaction. After the Joomla update everything works but the transfer to paypal.

The code used to transfer to PayPal is put in a Show Thanks Message action

<script type='text/javascript'>
window.addEvent('domready', function() {
  $('form1').submit();
});
</script>

<form id="form1" action="https://payflowlink.paypal.com" method="post">
<INPUT type="hidden" name="DESCRIPTION" value="Book Order">
<INPUT type="hidden" name="LOGIN" value="ourlogin">
...

I have discovered that form works when is loaded in a YooTheme ZOO article, but does not work when loaded in a Joomla article. I am not sure why.

Hi Warren,

That JavaScript snippet looks as though it was written using the MooTools library which Joomla! used until Joomla! 3 when it switched to jQuery. I suggest that you try re-writing using jQuery syntax instead.
