Well, I'm not sure I understand exactly what you're trying to see. But I never, ever, use "die" in Drupal; and very rarely "echo."
I'm seeing the right output. The client wants to submit a form, and then see a certain .tpl file, populated with data based on his inputs. It works fine. Just wondering if there's a slicker way.... :)
I thought maybe of changing the callback to a regular function and then have that check if it should be a form or regular output.
