submitting multiple items to paypal cart at once with php

Question

I have some items for sale that have 2 and 3 levels of customization. Once set the user adds them to my onsite cart. Problem is, how can i send each item to paypal on checkout? The only code ive found for dynamic buttons supports only a single item.

<form method="post" action="https://www.paypal.com/cgi-bin/webscr" target="paypal">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="add" value="1">
<input type="hidden" name="business" value="EMAIL">
<input type="hidden" name="item_name" value="Item #1">
<input type="hidden" name="item_number" value="123456">
<input type="hidden" name="amount" value="7.00">
<input type="hidden" name="shipping" value="0">
<input type="hidden" name="shipping2" value="0">
<input type="hidden" name="handling" value="0">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="return" value="http://www.yoursite.com/thankyou.htm">
<input type="hidden" name="undefined_quantity" value="1">
<input type="image" src="http://images.paypal.com/en_US/i/btn/x-click-but22.gif" border="0" name="submit" width="87" height="23" alt="Make payments with PayPal - it's fast, free and secure!">
</form>

I tried adding

<input type="hidden" name="item_name_2" value="Item #1">
<input type="hidden" name="item_number_2" value="123456">
<input type="hidden" name="amount_2" value="7.00">

But no positive result.

Any ideas?

Why don't you send the total amount your client has to pay to PayPal?
