Hi, I'm trying to figure out how a shopping cart is working in Zope. I've looked at the "Shopping Cart" Example in Zope (2.5.1). The "index_html" is in ZPT language and I rewrite it as a DTML Method/Document. The page seems to work until I push the "Add Items" button, on the next page I get the error message: Error Type: KeyError Error Value: standard_html_header Here is the contents of my "index_htm" page (only the "Add item" part): <dtml-var standard_html_header> <h2>Add Items</h2> <form action="addItems"> <table cellpadding="8" cellspacing="0" border="0"> <tr align="left" class="normal"> <th>Item</th> <th>Description</th> <th>Price</th> <th>Quantity</th> </tr> <dtml-in getItem> <tr valign="top"> <td><dtml-var "_.getitem('sequence-item')['title']"></td> <td><dtml-var "_.getitem('sequence-item')['description']"></td> <td><dtml-var "_.getitem('sequence-item')['price']"></td> <td> <input type="hidden" name="orders.id:records" value="_.getitem('sequence-item')['id']"> <input type="text" name="orders.quantity:records" value="0" size="3"></td> </tr> </dtml-in> <tr> <td colspan="2"></td> <td colspan="2"><input type="submit" value="Add Items"></td> </tr> </table> </form> <dtml-var standard_html_footer> I've left the rest of the scripts unmodified. What could it be? Thanks in advance, Rares _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
