PayPal HTML form with select drop menu - paypal

Question

I am trying to figure this one out, but I need some help.
I want to offer multiple products in the select list for a customer to choose and buy one.
<FORM action="https://www.paypal.com/cgi-bin/webscr" method="post">
<INPUT TYPE="hidden" name="cmd" value="_xclick"/>
<INPUT TYPE="hidden" name="charset" value="utf-8"/>
<INPUT TYPE="hidden" NAME="return" value="http://www.albertamomentummassage.com/gift-certificate-thank-you/"/>
<INPUT TYPE="hidden" NAME="rm" value="2"/>
<INPUT TYPE="hidden" NAME="currency_code" value="CAD"/>
<INPUT TYPE="hidden" NAME="business" value="daniel_1329709715_biz#gmail.com"/>
<select name="os_0" value="Therapeutic Massage">
<option value="2 Hour Masssage">2 Hour Massage $160.00 CAD</option>
<option value="90 Minute Massage">90 Minute Massage $120.00 CAD</option>
</select>
<input type="hidden" name="option_amount0" value="160"/>
<input type="hidden" name="option_amount1" value="120"/>
<input type="submit" src="http://www.paypal.com/en_US/i/btn/btn_buynow_LG.gif" />
</FORM>
Once I got redirected to PayPal I am missing, both, item description and item price.

You'll still need to send along an item_name field. The drop down list acts as a modifier for an item to add to the cart. In addition to the drop down list itself, you'll also need to send option_select(n) and option_amount(n) in your form. Check out the example below, it's from the Paypal button generator and should get you rolling.
<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="Yourbiz#gmail.com">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="item_name" value="Massage service">
<input type="hidden" name="button_subtype" value="products">
<input type="hidden" name="no_note" value="0">
<input type="hidden" name="currency_code" value="CAD">
<input type="hidden" name="add" value="1">
<input type="hidden" name="bn" value="PP-ShopCartBF:btn_cart_LG.gif:NonHostedGuest">
