I have a page with lots of paypal add to cart buttons.  For each of these buttons I want to have two radio buttons that will update the value of a span to reflect the price of the selected option.  So I have:

1. <form action="https://www.paypal.com/cgi-bin/webscr" method="post" id="buyform1" >
2. <input type="hidden" name="business" value="email@email.com" />
   <input type="hidden" name="cmd" value="_s-xclick" />
3. 
   <input type="radio" name="os1" value="30ml" checked="checked"  />30ml
4. <input name="os1" type="radio" value="100ml" />100ml
5. <input type="hidden" name="on1" value="Some Item" />
6. <input type="hidden" name="option_index" value="1" />
7. <input type="hidden" name="option_select0" value="30ml" />
8. <input type="hidden" name="option_amount0" value="6.49" />
9. <input type="hidden" name="option_select1" value="100ml" />
10. <input type="hidden" name="option_amount1" value="12.99 />
11. <input type="hidden" name="currency_code" value="GBP" /><input type="image" name="submit" border="0" src="images/buy-now.gif" alt="PayPal - The safer, easier way to pay online" />
12. </form>
13. <span cass="price">£6.49</span>
    

As you can see the price span is merely for information purposes and doesn't have anything to do with how the button communicates with Paypal.

I have found a number of different scripts to update the value of the price span according to the radio buttton selected, but I need something that will work with the same script and without having to specify a different class or id for the price span on each button on the page.  Is this possible?
