Display form results on same page as form (allowing to quickly edit)

[eluser]mfroseth[/eluser]
I'm building a rate calculator for insurance rates which can be seen at http://newco.ratecal.info

Right now the data is submitted and brought to a new page (results). I would like to display the form on the same page, allowing for them to easily update rates requested, etc...

In CodeIgniter, how do I go about duplicating the form, but preopulating the fields with the data submitted? I have the data stored in a session and can pull that but I am unsure as to how I can place that value in the texboxes, drop downs/radio buttons.

I'm using the form helper.
