HTML_Quickform_Controller

I have three pages in a Quickform_Controller that used to work. I must have changed something. Now, when I submit the first page, I get the same first page back but with everything I submitted in place. There are no errors displayed on the screen, nor are there any in the error array in the controller object. When I breakpoint in the second iteration of the calling page, I see that all the values are in the $_POST array. How in the world do I debug this? </edg>
