paying for multiple items (at once) via paypal

Question

I have a list of products that i'd like to add a "pay now" button to so that i can allow my customers to pay via paypal.

I've gone through the documentation and can't find how to do this. I can add multiple items, but this is no good as i already ahve the list of items to process. I also need the checkout process to itemise the order, so a "buy now" with 1 price is no good either.

Any help appreciated guys, i tried (with no luck):

<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="business" value="[email protected]">

<input type="hidden" name="item_name" value="test 1">
<input type="hidden" name="item_number" value="1">
<input type="hidden" name="item_name2" value="test 2">
<input type="hidden" name="item_number2" value="2">

See this sample and make the changes to yours accordingly. Basically add underscore to item name before number and give unique name to amount also with underscore and number.

You have to give amount to each item based on your carts totals.

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="[email protected]">
<input type="hidden" name="currency_code" value="US">

<input type="hidden" name="item_name_1" value="beach ball">
<input type="hidden" name="amount_1" value="15">

<input type="hidden" name="item_name_2" value="towel">
<input type="hidden" name="amount_2" value="20">
