PayPAl shopping cart

I am trying to write a javascript code to replace the Pay Pal shopping cart button but am not getting anywhere fast.

The html code I am trying to replace is:

<form target=”paypal” action=”https://www.paypal.com/cgi-bin/webscr” method=”post”>
<input type=”hidden” name=”cmd” value=”_cart”>
<input type=”hidden” name=”display” value=”1″>
<input type=”hidden” name=”bn” value=”wa_dw_3.0.4″>
<input type=”hidden” name=”business” value=”[email protected]“>
<input type=”image” name=”submit” src=”http://images.paypal.com/images/view_cart_02.gif” border=”0″ alt=”Make payments with PayPal – it’s fast, free and secure!”>

</form>

Thanks in advance for any help
