  1. First change the `on_sent_ok’ to:

    on_sent_ok: 'my_redirect();'

    then create that my_redirect() function in the page that displays the form:

    <script>
    function my_redirect() {
        var price = document.getElementById('PRICE_FIELD').value;
        var url = 'https://www.sandbox.paypal.com/us/cgi-bin/webscr?cmd=_xclick&business=xxxx@india.com&currency_code=USD&amount='+price+'&return=http://http://cratecreative.com/norpac&item_name=contribution';
        window.location = url;
    }
</script

    and done!
    Just make sure that you correct the email in that url and replace PRICE_FIELD with the actual id of the price field.

  2. This whole code goes in the additional settings box, changing the “xxxx@example.com” to your Paypal email and the "amount=100" to your own amount ex-"amount=25" or "amount="50". Also be sure to change the “return” page to your own URL once they complete the payment:

    on_sent_ok: "location = 'https://www.sandbox.paypal.com/us/cgi-bin/webscr?cmd=_xclick&business=xxxx@example.com&currency_code=USD&amount=100&return=http://http://cratecreative.com/norpac&item_name=contribution';"
