Hi,
I have setup a single item 'Pay Now' button, copied the code to my ASP/VBScript website.
Then I added the line:
<input type="hidden" name="item_number" value="<%=iAdvertID%>">
So it looks like this on view source:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="C6QCPZKNU39WL">
<input type="hidden" name="item_number" value="31">
<input type="image" src="https://www.paypalobjects.com/en_GB/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online.">
<img alt="" border="0" src="https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>
How ever when we send a payment through and look at the email receipt item_number does not appear anywhere on it.
Thanks
