Hello again I´m still testing the usability and reliability of Zope. To accomplish this goal I am developing a very very simple shopping cart. But I got troubled by something aparently simple. This is the code: <dtml-in "SESSION['cartItems']"> <dtml-in "sqlSearchProduct(productID=sequence-item)"> <tr><td><dtml-var productName></td><td><dtml-var price></td></tr> </dtml-in> </dtml-in> SESSION['cartItems'] is an array created in another DTML document using the well known SQLSession product. Here I am retrieving the itens of this array and passing it to a ZSQL method to get the selected items. The sqlSearchProduct, alone, works well. If I substitute the inner <dtml-in "sql...> for a simple <dtml-var sequence-item> the block works fine, otherwise it gives me the following error: Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: sequence Anyone knows what is going on? I think this must be a simple thing. Thanks []´s Fabio Akita - Developer F/Nazca S&S / Adversiting akita@fnazca.com.br
