Payapal pass-through variables

Hi

I'm trying to use pass-through variables with paypal - the variables 'item_number' and 'custom'.
this is my paypal form:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top" id="foo">
      <input type="hidden" name="cmd" value="_s-xclick">
      <input type="hidden" name="hosted_button_id" value="XXXXXXXXXXXX">
      <Input type="hidden" name="item_number" value="<%=idnum%>"/>
      <Input type="hidden" name="custom" value="<%=gender%>"/>
      <input type="image" src="https://www.paypalobjects.com/he_IL/IL/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal">
      <img alt="" border="0" src="https://www.paypalobjects.com/he_IL/i/scr/pixel.gif" width="1" height="1">
</form>

it seems that the transaction is going OK, but when I do:
<%=request("custom")%>
<%=request("item_number")%>
either at my success.asp page or cancel.asp page - I don't get any values.

What am I doing wrong?

You're using a hosted button, so details like that would have be included in the button creation wizard.  Alternatively, you can go back into the button to edit it and disable the "save button at PayPal" option.  Then you can add extra parameters to the button code and they'll pass through as expected.  

That said, if you say you're not getting ANY values then you may need to enable PDT/Auto-Return in your PayPal account profile.  I would recommend using IPN (Instant Payment Notification) instead, though, as there's no guarantee the user will make it back to your site even with Auto-Return enabled.
