Developers: The pass-through variables in the following HTML form come back to my site with null values. Either these variables do not come back to the site at all (in which case I need to know which variables can be passed back to my site) or I am using the wrong code with which to retrieve the variables once the user returns to my site. Here's the HTML form (specific URL references removed): <form action="https://www.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_xclick"> <input type="hidden" name="business" value="[my business email address]"> <input type="hidden" name="item_name" value="<%= itemName %>"> <input type="hidden" name="amount" value="<%= Basket[4] %>0"> <input type="hidden" name="invoice" value="[a random number]"> <input type="hidden" name="custom" value="[another random number]"> <input type="hidden" name="no_shipping" value="1"> <input type="hidden" name="no_note" value="1"> <input type="hidden" name="return" value="[a URL on my site]"> <input type="hidden" name="cancel_return" value="[another URL on my site]"> <input type="hidden" name="rm" value="2"> <input type="image" src="../images/bluediam.gif" class="input_image_props" name="submit" alt="Make payments with PayPal--it's fast, free, and secure!" value="I agree"> </form> I am assuming that variables "invoice" and "custom" can come back to my site and that I retrieve them using request.getParameter(variable_name). What's wrong with this? David
