Paypal item question

[dunvar]

I am working on a site that when a product is bought, it send the info to paypal and I am new to how paypal works with sites. It list everything in the item field on paypal's site and it looks bad. I am trying to get some of that information into the option field, but I am not having any luck. I can get it to do it in a js that I am using for multiple color and size on one of the items and it works.

I have some items that there is just one this, but I would like for some of that info in the option field. When it is one thing to select, I am using form with tables and have add the "on0" value, but it won't place anything in the options. Can anyone help me?

Here is the code I have,

<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="image" src="addtocart.gif" border="0" name="submit" alt="Make payments with PayPal - it's fast, free and secure!" width="79" height="25">
<input type="hidden" name="add" value="1">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="business" value="customers email address">
<input type="hidden" name="item_name" value="Colored Nail Files">
<input type="hidden" name="on0" value="Set"

<input type="hidden" name="amount" value="26.00">
<input type="hidden" name="no_note" value="1">
