  # # Name : example3.prof # # Description : WebKeystone script that illustrates how # to handle lists on an ordering form. # # Check for correctness of email address IF "Email" in ErrorVal RETURN RAW "Sorry, your email address is incorrect. Please go back and correct it." # Remove all blank values from the list named 'Quantities' IF f.some(Quantities) FILTER Quantities ELSE Quantities = [] # Check to see if the list named 'ItemNames' exists. Since the list is # created with checkboxes, there is a possibility that the list will not # exist. IF exist('ItemNames') # Make sure the number of items matches the number of quantities. IF len(Quantities) != len(ItemNames) RETURN 'examples/example3Fail.html' ELSE # Send email if an email address was entered.
