You are probably correct. If I change the "action" to point at my own form input testing page: http://www.dscpl.com.au/projects/vampire/examples/templates/ form_values.html and don't change anything, I get back: Form Values Name Value address1 leave the above blank address2 leave all checkboxes blank job_title So yes, "products" doesn't display if there is nothing selected. This though appears to be because the browser doesn't send it, not that mod_python ignores it. You can see this if you use a GET request and set "action" to: http://www.dscpl.com.au/projects/vampire/examples/templates/ request_details.html Note how "products" isn't even encoded into the URL. Looks like your handler is going to have to explicitly handle that case. This would not generally be a problem if using a scheme which mapped form arguments to actual function arguments like in publisher or Vampire as you could specify a default value of None for products and use that this pick up that it wasn't set at all.
