I have a pulldown menu for a single item purchase. This pull down menu is populated with numbers 1, 2, 3, and 4. I want to set the <input type="hidden" name="quantity" value="xxx"> value to what is selected from the pulldown menu. I don't want the buyer to be able to change the quantity once he gets to paypal's page. Is this possible? This is what the html looks like so far: <form action="https://www.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="quantity" value="1"> <input type="hidden" name="cmd" value="_xclick"> <input type="hidden" name="business" value="myaddr@addr.com"> <input type="hidden" name="undefined_quantity" value="0"> <input type="hidden" name="item_name" value="My stuff, 1-4 of 'em"> <input type="hidden" name="item_number" value="1"> <input type="hidden" name="amount" value="5.00"> <input type="hidden" name="currency_code" value="USD"> <input type="hidden" name="no_shipping" value="1"> <table><tr><td><input type="hidden" name="on0" value="Number of items">1-4, $5.00 each</td><td> <select name="os0"> <option value="1">1 <option value="2">2 <option value="3">3 <option value="4">4 </select> </td></tr></table> ****THIS IS THE VALUE I WANT TO SET TO WHAT WAS SELECTED IN THE ****PULLDOWN MENU!!!! <input type="hidden" name="quantity" value="1"> <input type="image" src="https://www.paypal.com/images/x-click-but23.gif" border="0" name="submit" alt="Make payments with PayPal - it's fast, free and secure!" > </form> Can anybody PLEASE help me?

[br]Delete: &lt;input type="hidden" name="undefined_quantity" value="0"&gt;

That flag works by presence or absence, not its value. There may be an error in the documentation.

OK, so if I delete that, how to I change the
&lt;input type="hidden" name="quantity" value="xxx"&gt;
to whatever item the end user selects in the pulldown menu?

[br]&lt;select name="quantity"&gt;
&lt;option value="1" selected&gt;1
&lt;option value="2"&gt;2
&lt;/select&gt;
